No, anyone can post and I'll help them.... but I don't see any refunds on your account either.
I just don't think your tone mocking another customer and calling his posts "crap" is appropriate. These forums should be used for asking questions and answering them. Your posts don't seem to match that criteria regardless of your purchase history.
Make somebody's day and help them solve a problem. I won't care if you ever tried to use a webassist product or not. Come in calling somebody's ideas dumb and mock them and I'll have a problem even if you own all of our extensions.
