It's a banned user that comes on and throws some horrible abuse around. He used to have variations of 'Klown' as his user name. Could be called anything at the moment...
All you need to know is that they are the lowest form of turgid pond life you can ever imagine, and should be permanently banned from this site, as no place for them here.
They can go and be lonely over on SAB, which is a site where nothing much ever happens apart from banned users from past years here, boring each other to tears.................i only miss one from past times and he was a pudding.
