There have been a TON off bots trying to play that "I follow you, you automatically follow me" game for MONTHS here. I, for one, am not sorry to see them purged. They don't read. They don't make you look wildly popular (who the hell really reads and follows based on numbers, anyway?) They're mostly spammers, purveyors of drugs or Bitcoin, or scrapers trying to make a buck off what YOU write. Good riddance to them.
