Do people honestly evade bans just to spread FUD? Do they have nothing better to do with their time?
Yes. Some trolls are very determined and that's how they get their kicks so it's not a waste of time for them. NLC has has had hundreds of bot accounts and dozens upon dozens of 'active' troll accounts banned. He's also the reason why newbies can't post images because he was spamming the forum with gay porn jpgs.
I really can't tell whether he's made a lot of money from bitcoin or lost a lot (or possibly both), but either way he's just a troll.
