Chribba had originally written this comprehensive analysis of Jita chat stats in the official EVE-O forums, here it is reposted – I encourage you to read.
Analysis: Six Months in Jita by Chribba
Some of you may remember my previous Jita chat analyzes, the 24 hours in Jita report as well as the One week in Jita report.
So with years passed by, what happened, how does it look, is spamming in local any concern?
tl;dr – Jita is full of spam, and spambots. Just like before.
For all that wants to look at numbers and stuff themselves without reading my boring text, the link is below.
Six months in Jita (table columns are clickable for sorting)
So, what did I find?
Much like previous times, there’s a ton of talk, a lot of it what appears to be highly automated (something also pretty much confirmed).
The period analyzed is from 2012-01-01 until 2012-06-30. During this period 79,787 different pilots were found, together speaking 3,204,660 lines of chat, an average of 12,2 lines/minute, or roughly one line every 4,9 seconds.
The “in depth” analysis has only been made towards the top 100 speakers in terms of number of lines spoken.
And not surprisingly, the top 100 pilots do speak a lot – they among themselves are responsible for 30,4% of all chat in Jita during the entire period. So roughly every 3rd thing said in Jita at any time during these six months will come from one out of those 100 people.
With the top person saying 1,83% of all that’s said in Jita – Samantha Marley. So then you might say, sure but there are people that speak a lot, discussing world news, politics, their daily life, and yes actually there are a few among those top 100 that do. In the case of Samantha though, she spoke 58,724 lines in total, but only 40 different things were said, and also she were only active for a total of close to 100 days out of those 182 days analyzed (but then she’s a confirmed bot as well).
What do I mean by confirmed bot?
Ok this one is tough, I can’t really confirm a bot, I’m not CCP, I have not really any say about bot or not (and i’m sure some people might find themselves on the list and go I’m no bot – and maybe you’re not). What I mean by confirmed bot is that in my best judgement looking and posting characteristics, both what’s being said, how many times it’s being said, and how often, posting timers, I am fairly sure that the person is posting with the aid of some type of software.
An example would be a pilot that consistently is able to post a few lines per minute for hours and hours and never missing to post or a person that posts their messages exactly 73 seconds apart, not missing to hit that spot over and over – possible for a human, probably but highly unlikely.
So there you have my definition and how I reason when I’ve put a “Yes” under the bot column.
So onwards there is a graph showing how much is said each day and it goes a bit up and down, and interestingly to see the Goon’s burn Jita causing a HUGE spike that “out-talked” the spammers by far 
To this we also have a list of what’s being said the most times, overall, looking at chat from various channels and hubs, words like “lol”, “hi” “:)” are usually at the top places – not in Jita of course.
In Jita, the phrase “[Multiple Items]” was said the most times, 113,639 times by 4,249 different pilots – that’s not surprisingly though, it’s a trade hub after all, the biggest even.
However, the second most thing said is “30 Day Pilot’s License Extension (PLEX) x 3 1.2b” – now this is not shown here since contract links only work in-game, but it’s a scam contract, said 47,542 times, by 11 different pilots!.
Same goes for 3rd place, “[Want To Sell PLEX 388Mill]“, said 29282 times by 11 different pilots.
First on 4th place we find the common “lol”, being said 21,808 times by 8,267 different pilots.
So what does all of this mean? Well probably mean nothing to most since you might already have commented below saying minimize local, or who reads Jita, there’s a thing called block – before even getting this far 
But for those who did read this far, in my opinion this shows that spamming, with or without bots isn’t being dealt with at all.
Who should deal with it, well I would for one feel CCP can spot spambots quite easily and just looking at my list and seeing how much is being posted by these bots local spam can be drastically lowered with simple means.
I feel, that this kind of use of local ruins social aspects of EVE and our communication, I am seeing this grow and becoming more of a problem, while I see no actions from CCP’s side. I see the same spambots that I reported over and over again, still posting there things every 20 seconds, even after being reported the first time 2 months ago.
But that’s all for this report, you can see many things in the research link above for yourself and I’d be happy to try and explain and answer any questions you might have.
Maybe we can hope for a bit less spam in 2013, but looking at trends, it doesn’t seem likely.
WOW! All I can say is amazing work… or was that done with a bot ?
probably parsed the chat log of jita local
Confirming you just accused Chribba of botting.
who reads jita
Block two dozen spam-bots and its shockingly quiet…
this never would have happened in Yulai
So what do you do, when you are probably the most famous person in EVE, incredibly space rich, the only single person who got his own community spotlight from CCP? You start reading Jita local.
Awesome read actually
"Awesome read actually
"
I mean Chribba's article, not Jita local…
There should be a "post once every 5 minutes" limitation in jita local or something.
Absolutely or something like:
if post# in local > 30/h —> flag
Agreed, why is valuable server time wasted on this shite in Jita when we have to suffer 80% TiDi in fleet battles above 200.
Is this what CCP wants? Keeping scammers with a nice response time while the dedicated players of EVE suffer horrendous lag.
When you bridge across systems with fleets of 150-200 and half the fleet gets there and then you wait for a minute for the other half to bridge.
CCP is quite capable of making jita local a special case, afterall the hardware resources are a special case. Put some time and effort into fixing this so that you can take away all that hardware and use it for something that it was actually intended for.
Seriosuly, did the creators of this game envisage so much of their resources going to a shopping centre instead of the battelfield?
if you do that you may as well not have a Jita Local.
Post every 30 secs, is fine. But the easiest way is to not allow the same exact characters repeated every 5 secs like now.
Or make it so if you link anything, that same exact item contract player name etc can only be done every 3 minutes. That means normal people will copy paste there contracts and it will have the same item yes but different characters in different order, meaning a person on the fly is changing the post.
I work now with Python/C+ alot and making a script to not allow the same exact message over and over is easy as pie…..Truth is CCP gets to brag how much people chat in local and have server logs to back it up so when they advertise to VC`s for funding on projects like Dust and that vampire game they can show them just how active local in Jita is meaning to a avg investor, "Wow this game is massively not just in scale but in player content [Eve-Kill,Battle clinic,Eve mon, EFT] and is also never quiet in local" These players must really be busy and so in depth in game and so devoted to selling items and getting rich they will try to sell a ship or scam for 6 hours straight.
CCP wont block it for the same reason they wont Nerf/Tax Blues, yes it slows the game up and is detremental to fights having 5k players on grid, and now in TiDi in almost 100% of fights, but who cares the players are already junkies who will whiine but not do much else and these blues take in brand new players thus making more of a player base stick around.
So the current players its worse but for investors of massive projects like Dust and other things like millions they need in server upgrades etc, it helps to show fights with 3k members on both sides….It makes it look epic when in reality u can pop and not know it for 3 hours.
Nerf/Tax Blues Nerf/Tax Spam Bots Nerf/Tax mining Bots…..Sorry but all of those are in CCP`s favor and unless it really really pisses us off, it wont change.
More proof that chribba is the "best" player in all of New Eden
agreed. block a couple dozen folks and it gets very quiet in Jita.
Oh noes, Jita is not comfy enough, I almost feel sorry for all those sellers, re-sellers, re-re-re-sellers, who have no ISK to fit their 30 bil suicide ships…..I feel like donating another 1 ISK to a moron who will move 30 PLESK in his frigate….
Testing.
What was wrong with the server all day?
CCP needs to police up the bots. Simple as that. Their impact on the game is negative in every way.
riverini have you looked at the sov map today? WRITE SOMETHING!!!
I like that Jita is full os spammers. It gives a text feel to a market place where people shout "BUY MY SHIT" , or "FRESH FISH".
The spammers are just the obnoxious vendors with loudspeakers and playing bad music over and over because they only found one piece of music they like
You remove that, and jita is just another clinically silent video game location.
Bot spamming has been going on for years and years, mostly done by scammers who probably then RMT the scammed isk
CCP, tax Jita local chat, that bots, prequently spamming local would lose a lot of isk. Thank you.
Trials are not an issue. Trials cannot trade to paid or xfer isk. These are alts on paid accounts my friend.
wasnt a war on bots but a war on RMT, even if found botting if you dont RMT your safe (the DEV blog was informative if dissapointing)
so if thats thier approach to botting, spam bots i rate would fall next to market bots at the bottom of thier list….
