Well, repeat contacts where I did not like a previous chat. Basically, a chat where right as we start they go right to, "what would you like to do to me?" Or thereabouts. I love good dirty nasty chats but a little more imagination is needed. So when I see them requesting a chat I feel it is best to ignore it. If I were to tell them I did not want to chat I might upset them and I do not need to be doing that.
