>>30591682I really doubt you can get banned for something someone else already got online and past the box check with.
I've seen TONS, just TONS of injected ones while I've been tossing my breedjects into wonder trade. I delete all of them, personally, but I doubt anything bad can happen, and I know I've had at least 50 hacked mons go through my box in online mode. 3 hacked magearnas so far, I got one on my very first wonder trade weeks ago.
I'm also playing on hacked .code and have injected things like utterly illegal mons with megastone to fuck around with, or illegal legendaries like Arceus / Mewtwo.
***Note that I HAVE released these before going online.
They don't seem to stain your save file or flag you or anything though, I've never even seen a short tempban.
