Unfortunately, stupidity and annoyance aren't necessarily against the terms of service for the site. espola really hasn't done anything to warrant official sanction (there are a detailed list of offences). And historically, problem posters in the past have been given a LOT more rope before they were dealt with (LY, wbu, PV, etc.). So no banning is coming in the near future. I would just keep shouting him down until people get the picture or put him on ignore.
