There's only so many words that start with ATCG that make properly verbose and pretentious chumhandles. Plus, mine shortens to AQ, which just makes sense. Not that anybody is actually using it anymore.
I wouldn't be too concerned about Karkat banning himself from the bulletin board. Even supposing that the system tracks the same person at two different times as two separate accounts (which it looks like it does, somehow), the whole point of using Trollian as a chat client is that the user can't be banned. Or was it that Sollux used his apeshit bananas hacker skills to unban themselves? In which case, he probably just unbans Karkat from his board.
Unless this is Hussie setting this up as why Karkat trolls the kids backwards in time. But that still doesn't make any real temporal sense, and is way too straightforward. Like CG said way back when, he planned it that way, presumably after they all got trapped on the asteroid. In other words, Karkat's just doing his trolling incompetently because he's Karkat, which seems more likely to me.
Was anyone else a little weirded out by Sollux "laughing" in his post? Seems out of character to me. And now we know he's the biggest hero on Alternia.
