When people are unpleasant or leave me hanging without resigning (usually because they are losing) or if I just don't like playing with them, I just add them to my blacklist. I have been playing for quite sometime and my blacklist has gotten pretty long, but it works well for keeping unpleasant experiences to a minimum. they still happen every now and then and it does really upset me, but it takes all kinds, I guess. One thing that is really weird is that some of the worst people, who have been on my blacklist for a long time actually have the nerve to put friend requests in and although I don't befriend them and they remaining my blacklist, their friend request doesn't disappear. Some of the early ones, a few, were actually trolls, who had no business being on the site in the first place and I can't understand why they haven't been eliminated. All and all these are just minor annoyances, because the blacklist thing really does work great.
