What IPO scam? Most people bought their NEM stake between $5 to $50 and currently hold stake worth $1000 - $1500. People everyday on this forum lose 100s, 1000s and 10,000s to real IPO scams.
Only thing UtopianFuture did was pad fake popularity back in January (those accounts he made were later taken off the list). Nowhere as bad as it sounds. Every new coin / project has sockpuppets advertising it. You have to, since this forum moves so far and obscure coins go to page 5 within hours.
