Fave and running can be annoying. I mean I get a few messages on some of my pics saying (insert name here) has faved (insert artwork name here). I go to their page and it has nothing to do with what I posted. I mean they could at least put a comment. It's probably just for attention. Really annoying though.
Ah sorry, then I misunderstood you I guess. I am not sure about this... Sometimes I can comment like 60 times without getting a warning, sometimes it's just 10 or 20 times I have no idea how it works. Maybe by similarity of the comments?!
