I see them early (EU) morning on Chaos when all is quiet...all level one going through their first quests. I'm sure it's been said before but it's very difficult to report them as they have horrible names and move so fast you can't always catch them. And you can't right click and report a character, only if they say something. Which these bots levelling up don't - so no real way to catch them.

But as has been said, that would only be open to abuse anyway with peeps reporting non-bots due to some quarrel
