Karen,
The clown behind this may not be using the shop's computer, but two hours after you posted on the thread that got yanked, the clook character emailed me thanking me for more emails. I'm not sure what he meant by that, but he does still have access to a computer.
I think the easiest solution is to mark his emails as spam - report spam - whatever the feature your provider uses, and we shouldn't see anymore unwanted emails from him.
Michael, the guy has a strange sense of humor - and I hope that's all it is. I can't blame you unless you're taking part in actually sending the emails. Your apologies show you're a nice guy, but they are unwarranted.
