Look mate, the key to establishing a believable supporter profile on a rival messageboard is to be subtle, go slow and ingratiate yourself without too much fuss. Just don't overdo it eh? You don't come on and say "I HATE WEDNESDAY ME!!! LOVE WILDER, LOVE HIM TO DEATH. Love United, but hate that McCabe bloke. We'll spend no money, but we should BUY A WEDNESDAY PLAYER!!!! But, I HATE WEDNESDAY!!!!!" No one is believing this schtick as enthusiastic as you're being. 10 out of 10 for effort.
I'm prepared to give you a second bite of the cherry. I'll pretend these first 40 posts never happened. I like the oddness of the character you're pitching, but you're going to have to dial it down a couple of notches.
Right, have another go. You can do it x
