I don't deliberately go look at them myself but I do sometimes go into the AH when I have one of my mules as my selected character and the AH will recommend me some items (usually boots). Given that my mules are only levels 2 or 3, the items being recommended have got no level requirements... and many are going for a fair bit!
Are they actually selling though? Or just being posted up at extreme prices? That happens in WoW. People buy gold from gold farmers and then post petty items up on the AH for huge prices which the gold farmers then buy...
