Has anyone heard of this guy on ORAS, XY, SM, and USUM named AdventureSnivy or whoever?

Don’t trade with him, especially on SM/USUM, all of his Pokemon up for trade are hacked and will cause your game to basically be erased—the only way to fix this error I’ve heard is to transfer all your Pokemon to PKMN Home, reset your game, and transfer them back—and if you don’t to suffer this: make sure the trader isn’t AdventureSnivy, is wanting a Snivy, make sure the gender or level don’t say anything like “Back” or “Options” and your Primarina will be safe
