What about them? It’s Jita man!
But on serious note, those chat bots that you might have in mind, this is something we are not looking at right now as there are other bots out there that need all of our attention.
But if you see somebody obvious, or a player who is really spamming, like if you see a behavior in the game, not just in Jita local, please report it to us via a Support Ticket so our GM’s and us can take a look at it, investigate and take appropriate actions.
