I didn't delete my account or any of my posts when I left Reddit. Felt too much like punishing Reddit users and searchers of random information and not enough like punishing Spez.
I dunno. Aside from "fuck Spez" (which, don't get me wrong, I can't say is entirely unappealing), what's the argument to be made for deleting your post history via something like PowerDeleteSuite rather than just leaving and never visiting Reddit again?
