There's nothing to worry about. He did say he doesn't intend to leave again. And here he also requests us to demand verification from him in his PGP thread if he leave it inactive like this and he suddenly starts posting:
I may soon be gone for a few days here and t here. If so, I will catch up when I return; don’t worry, I do not intend to disappear again!
If my forum account has posted recently, and significantly more than a month has passed since this thread was refreshed with a new PGP-signed, OTS-timestamped message containing verifiably recent information, then you should demand a fresh statement consistent in its evidentiary strength with the statements that I have previously provided. Be very suspicious if the demand is refused or ignored.
In fact these days I should be worrying more about myself instead of him.
- Nullius didn't join any paid signature, which he could easily have done to monetize the account. Hacking or buying an account to make quality posts without earning from it would be dumb, and the person behind the account doesn't strike me as dumb.
Actually he's wearing a paid Yolodice ad right now, But if someone ever hacks it and attempts to join another campaign, we would easily notice it's not him.
