Sounds to me from what Ratimov said that the whole section is not only bot-infested but pretty much dead anyway. The best option would be to just nuke it, no?
But does that ever happen on Bitcointalk? Do we have examples of child-boards being deleted completely because they aren't as popular as they once were? I would love if this forum had zero tolerance for scams, but since that isn't the case, then we shouldn't do anything about it. If it becomes impossible to post such crap in the Russian board, why are all kinds of scam projects allowed in the altcoin boards or the Investor/HYIP-based sub? Get rid of them all or don't do anything.
As for bot activity, the bounty reports are bot activity. You have examples of bots still posting their Facebook and Twitter reports months after the bounty ended and nothing is being done about it.
