That's a surprisingly light load... came across the #1 group earlier today... or, rather, a couple of them at the same time, and it seemed a little fishy.
The "misguided" get precisely one shot with me... a guided advice reply-comment that sending the same copy-pasta comment to 100 posts is spam, and here's a better approach to gain followers... ironically, the "advice" bit from me is ALSO copied and pasted boilerplate text.
It is pretty light. Now I'm down to sorting through the top commenters and weeding humans from bots. The bots (or humans acting like) providing a service get a pass with me. It's up to the community to decide if they like them. Same with novelty accounts like @ionlysaymeep.
I'm going to start looking at post spammers next.
