im not asking this because i hack, im asking this because i think i got a hacked pokemon in a trade. i migrated a probopass from diamond and it says im its original trainer (in diamond) but for some odd reason gts wont let me deposit it. so im thinking maybe i got this in a trade and gts finally banned hacked pokemon?
They...kinda did. Basically, if it's obviously hacked, you can't get it into the GTS. So, if the pokémon has 999 Attack, you can't get on the GTS with it. If it's a Magikarp with Fire Blast, you can't get on the GTS. If you have a pokémon with an egg move that wasn't hatched from an egg, you can't get it on the GTS.
However, if it's hacked well and has legal stats, movesets, etc. you can totally get it on the GTS.
Now with a Pokemon Online account! Sometimes I'll even accept challenges.
Sadly, they arent banned yet, since i remember seeing a youtube vid of a guy uploading Hacked pokemon that will corrupt your game up.
My guess is that it has to do with the new name filter, where they prevent any bad word from being uploaded. and Probopass has A$$ in the name. just like Cofagrigus, you cant upload it without giving it a nickname cuz of the F A G word in the middle.
