So what exactly would blacklisting me from DT1 accomplish if I left a false flag? This makes even less sense.
Dunno, maybe that's why he wants you "~"-ed instead of blacklisted so that you'd be gone from DT2 as well.
Good point. However, my main argument is that blacklisting me for this would destroy all the efforts he made to decentralize the system so far. Therefore, he chose that path. I would doubt any claim that he can't single-handedly blacklist on both levels.
since I did the opposite of what theymos asked, I guess I'll add theymos to my trust list.

Very fair deal, but my reasoning was far wider and superior than his.
He is providing you a decentralized solution, but you are refusing to follow the standards of that system and instead demand special privilege to abuse it. You only have yourself to blame.
