I was actually just going to comment on this point, Hiro. You are absolutely correct!

It takes almost no effort to find hordes of bots and campers. Most of the bots I've found in my casual shopping and exploring were in fact obvious bots--ruthed accounts with generic names in sequential order (usually with numerals in their name). At more than a few stores, the bots were actually NAMED "bot123" etc.

So to cite that bots no longer exist as a prominent user hour accumulator is just plain silly.

I've not found anything in the Abuse Reports dialog that points to specific "bot/camper" violations. Torley alluded to bot usage as a reportable offense, but I'm not sure if that is official or just his personal perspective.
