I have never put anyone on ignore in the forums, but I do it multiple times a night in the chat room. If people can't be respectful enough to read my private chat notice and follow it, then I don't feel they deserve the courtesy of an answer from me.
Yes, if there is a serious moderator request, I will listen and do what I can, but when it's a guy from a middle eastern country (not saying everyone from that area is bad, but I would say the majority of pm's I get are from that area) who only wants to talk to me because I'm a woman who shows up on the list, then no, sorry, it's not happening.
