If someone wishes to be abusive, it's not difficult to register as a new user, using any name at all - and invent an email address if so desired.I can't see how a post from such an individual would be any more 'valid'
What I very much dislike about the post from the 'guest' who started this thread, is that the link to the old thread is routed through a different site - hence displaying a banner advert at the top.
I've always loved the fact that the mudcat is banner free, and hope that this isn't the start of something...
