Did my Shiny Diancie come from a Japanese Event or is it Hacked?

Question

In a link trade I got a shiny diancie.
Name: Diancie
Type: Rock Fairy
OT: ShinyGTS.com

Exp: maxed
Lv.:100
HP: 242/242
Sp. Atk: 328
Sp. Def: 336
Speed: 199
Defense: 336
Attack: 212
Came in a cherish ball.
Moves: Diamond Storm, Moonblast, Psyshock, Hidden Power
Ability: Clear Body
Nature: Modest
Characteristic: Capable of taking hits
Ribbons: Alola Champion Ribbon, Battle Tree Great Ribbon
Description: A fateful encounter seems to have led it across space and time to reach you from the Kalos region.
I'm able to deposit on the GTS, does not appear as special Pokemon.
I think it may be hacked, sad thing is I traded my legit Shiny Shaymin for it.

Answer 1

It's hacked; Diancie can't participate in the Battle Tree and it has a ribbon from it (its not supposed to be Abe to get it)

Also, that is an incredibly sketchy OT name. Even if everything else was ok, I wouldn't trust anything with an OT like that.

Comments

Any OT that has .com or .bitdo, etc. in it is hacked. That part of the OT has to do with how the Pokemon was generated. :P
