Not Wario64. Wario64 was a general troll, harmless, but that spamming today was some super-calculated politically-driven disinformation shit.
It’s just supposed to be edgy. Spam stuff you’re not supposed to say, like slurs. Middle school stuff with some indication of modern SW being superior to older SW.
I don’t know Wario’s specific type of trolling as far as content. But he’s the one who gets off on making new accounts and using them at full speed before he gets banned, evading bans, etc.
