I've given this some thought, and there really are only two serious contenders for BOTW.
1. Fish Mitten
The obvious choice. Has moved on from The Rumour Mill - because, let's face it, it really wasn't - and has now become the bane of the classifieds. Avoid selling him stuff at all costs, as if it is not up to scratch he will stalk you like a crazy former girlfriend. And as for that user name - well, that joke isn't funny any more. Means well, but just gets it horribly wrong most of the time. Former Mod, but Mod powers were revoked as he is a bit of a loose cannon, to put it mildly. Unstable.
2. Ironhide
What can I say about Ironhide that hasn't already been said? For me, it's the user name that says it all. It MAY - and please note, I say MAY - be cool to be called Ironhide if you are 8.
He's 33.
I rest my case.
In the absence of any other nominations, let's proceed to a poll with haste!
