I've learned to not trust online entities naming themselves after historical characters, especially those of Third Reich leaders.
Years ago, after the Breivik psyop, I think it was Fjordman that got outed as a racial jew, and a bunch of online entities on some forums were also outed as Israeli shills. Many of these entities had handles like Joseph de Maistre, Vercingtorix, Richard the Lionheart (lol), and other historically themed usernames.
Same goes for usernames like The Celt, Alemannic, Spartan Warrior, a plethora of Viking names, Erik Thorson, Son of Odin, Wotanswolf, etc. Shills would try to fit in so hard to the point they would stick out like a sore thumb to those hip to the game.
Of course, nowadays they've switched to using faggoty meme-derived usernames (when not anonymous) like based fill-in-the-blank, george_costanza (likely a shill), Warrior of Kekistan, a reference to autism, and even niggerfaggot.
