They talked about it on the show a lot today, Maddox was one of the "maybes" but no theory was held higher than others
Reportedly the caller said he wanted to suicide by cop, meaning he hoped to actually get Dick killed which is highly vindictive
Maddox is vindictive but I don't get the impression he'd go that far
My best guess is a deranged Fuentes or Jessie PS fan
Recently someone trolled the r/thedickshow subreddit with some low-effort photoshops of dicks in Dick's mouth under the "I would suck a dick if it was big enough" quote that are deleted now along with the account, the posting account was obviously hacked, looked like a typical PodAwful joke (here's
one of them)
Internet wars ebb and flow, if there's been other recent trollings/hacks it would indicate what community is sperging at Dick the most right now
