It's not a democracy. It's a site that is the property of an individual. No matter how 'veteran' any user happens to be, he is still a guest. If you p*ss off a guy in his own house, don't be surprised if he turfs you out.
The catchphrase thing was a bit of fun mostly - there was banter in each direction over it and we all had a bit of a laugh. Fair enough it was annoying to see it in every single post, but you are right (IMO) that it isn't grounds for suspension (temporary or otherwise).
Winding up the site owner, posting endless self-aggrandizing bullsh*t (even if in jest it gets tiresome after a time), getting stroppy (again probably a backfiring joke) when some of that stuff was edited, refusing to heed any of the warnings given by the site owner, constantly moaning about it and generally behaving like a child, on the other hand, are perfectly acceptable grounds.
Complaining about how unfair it all is is rather pointless. Wayne pointed CU at the site terms and conditions and was told "I don't have time to read that, I'm far too important" (not verbatim, but to that effect).
If he had read it, he'd realise that he got off pretty lightly - it states warnings are almost always given, but not twice.
