Oh yeah, I'll still try to remember to report if I see they're on one of the big instances I already recognise, but otherwise I might not in case the report just goes right back to them (like it did with the exploding people) in which case I'm not exactly sure what to do other than post a warning, but I'm rarely the first to notice this kind of behaviour, nor do I really want that kind of spotlight, so I might not be comfortable doing a public announcement about it.

Edit: though I'll admit, I do often block people for things others might not consider as problematic, and feel like if I reported in those situations I'd just get ignored (and if the report goes to the wrong kind of person, potentially targeted for being "too sensitive" or whatever) which is why I'll often keep it to myself.
