>>51688819Im both-a shiny hacker and a shiny hunter.
I have really ridiculous unique shinies i hunted specifically just for fun. I used masuda method to legit hunt for legit shinies of weird mons with very unusual moves.
And those are perfect stats too.
So if you would see one online you would think that it's some random hacked shinie made by a kid in pkHex.
but it's legit.
Again - if its on GTS you can't tell. It might be legit but also might be hacked. But also there is a chance it's legit. 50/50
It's all based on your assumption only.
