What "treatment" did you have in mind? At best, Roko made a honest mistake, and the deletion of a single post of his was necessary to avoid more severe consequences (such as FAI never being built). Roko's MindWipe was within his rights, but he can't help having this very public action judged by others.

What many people will infer from this is that he cares more about arguing for his position (about CEV and other issues) than honestly providing info, and now that he has "failed" to do that he's just picking up his toys and going home.
