Eh, unless I've completely misunderstood everything here, the nuked member is the one who made the scam accusation and that obviously would not be grounds for a ban. 

Looks like the plagiarism did it, which is usually the case unless it's a ban evasion.  In this case neopotism was so new that he probably couldn't have been linked to an alt account that got banned unless mods are checking IP addresses or something, and I don't think that was the case.

Neopotism was annoying and good riddance.  What I'm wondering is who he was an alt account of, because if I recall correctly it was pretty obvious he was somebody's alt.  If that's true, then the main account deserves a ban, too.
