Not a one, using the ignore feature is the last refuge of the feeble-minded...
but I did block AKC years ago from sending me hate PM's cause my in-box was getting full, forgot how I did it though.
Not even close, at least not yet...he did cost us a top-10 1st round pick, but it was in a weak draft & we also picked up Kiko as a result. The key though will be in knowing when to cut your losses & move on.
