Now what did utopianfuture do for NEM: a whole damn lot! Only for the stuff he did on the frontstage he should have several stakes, let alone the stuff he did backstage.
This is true. UP did a lot of work, and he was getting a lot of reward too (more than ordinary stakeholders). It's not as if he was getting nothing. There was no need for him to use sock puppet and do stupid things as he was already getting rewarded. Your post seem to imply as he he did a lot of work, but was getting nothing back. He already collected 66 BTC and several thousand Nxt during IPO.
Plus you ignore that what he did hurts his credibility. He did the right thing by resigning. The whole thing would be forgotten soon in a week.
