Pretty sure he gravitated to Parler, which means he's been hacked. He's also a regular on Gab and Stormfront along with that weird Coyote lizard. He's posted just a couple times at TK since before the Insurrection, so the stories of him having no internet access may well be true. TK is his meth fix these days, so I don't really see him staying away.
So long as the Minefield is active as it is now, TK's presence is for the better. Case in point: While Lonaf was no where on the same level that TK overall is now, Lonaf 'died' when the NeoWastes forum was rolled into the main forums to encourage its user base (refugees from Portent's ChaosWastes) to mingle with the main userbase. Ultimately, it failed and the Wastoids then the Lonafites drifted away.
