I think LyingbastardMF is a lot more offensive than Yzzywuzzywhatver. The latter kind of comes across as that younger brother you want to smack in the face sometimes but don't because you know he'll get it together eventually. I don't think any harm was intended by the HTML thing, it was just a bit dumb.

LyingbastardMF on the other hand is an utter wanker! Go on Tony, ban him and I'll send you a fleece (Oh what a slippery slope!)
