I know the history, genius, but apparently you don't.
Because ackchyually his original username was "TobyDaPug". Get it right.
Also IncognitoGuy and BritishMormon really are two separate people. Yes we know each other, but he's not the same person as me. He's been away from Imgflip for years. He's been on other sites but I also think he's just busy with irl stuff and, to put it bluntly, grew out of all this. Like you and I probably should.
In case you're wondering I am WhiteNationalist/BritishMormon.
And MoonMan/Darth_Memeus is also a separate person. He's a friend of mine, but not friends with Toby/IG. "Moonie" as you call him has just taken another one of his many supposedly permanent departures from the site.
I believe Toby/IG knew at least one other user (Pollard) irl. Probably a friend or relative.
Also a lot of the supposed alts of Toby/IG, WhiteNat, and BM were (often quite blatantly) fake and just set up by his (and my) many enemies on I_P (most of them mods of the stream and/or site).
