If you pm me about sig spammers, rest assured, I do read them all and check them out. Some go on my "watchlist", some I act on. I don't generally respond to such pm's though, I don't really like discussing actions taken against users with other users, and I don't have time to respond to all the pm's. If you've pm'ed me about such users and haven't gotten a response, don't let that discourage you. I know it sucks to not get a response, I really do, I've been there. It feels like the pms are going into a black hole, and it was a waste of time. Just treat it like reports, send a pm about it and move on, I'll deal with it if it's needed. I do appreciate it, I get a lot of pms (have almost 6k pms in my inbox) but I think this is important.
