UtopianFuture did not scam anyone.  What he did was equivalent to buying fake likes on Facebook and Twitter.  All he did was create sockpuppet accounts, to pad popularity in the initial weeks of NEM, and he later took them off the stakeholder list.  This is a tactic done by practically every coin out there.  Satoshi likely had a dozen aliases in 2009 to promote Bitcoin.

Think hard about it - UtopianFuture had nothing to do with the taint analysis (others were in charge and it was open to anyone willing to volunteer).  If UtopianFuture still had his sock puppets then he would had been busted hard, no way (under any fantasy scenario) could he had kept 100s of sockpuppets (let alone a dozen or five of them).

UtopianFuture at best probably only had 2 to 5 sockpuppets total (later removed) but now he has zero and persumably no developer stake anymore.
