I love how he still doesn't understand how to hide his tells, it's incredibly easy to stop saying foxdicks so much, or stop posting decade-long memes. Many people who are much younger than him post in the chans everyday without giving themselves away like that.
Actually "foxdicks" is a /cow/ wordfilter for "Kiwis". Tells that are obvious Hirtes are posting boomer-tier reaction memes or image macros from like 2002 (as you said) and complaining about Null, @yawning sneasel, and Drumpfy.
One thing that was seriously strange was that when /cow/deleted his posts, some thread OPs vanished as well, if they were indeed of his making, then it might be worth looking into those cows because maybe there's some Hirtes cocks there.
The one thread OP that vanished was on a Nicholos Foxworth/Federov associate named Choji who's some edgy anime discord tranny. That's too hip to have anything to do with Mike, was probably a different ban evader, maybe even Foxworth himself throwing someone under the bus to get heat off him? Who knows.
