How is this different from what they did in Gen 6? It's NEVER the pokemon since they don't let bad hacks online anyway ("There is problem with one or more of your pokemon!"). These blacks (I won't even call them bans, because they aren't. You can start a new save and reverse it) are only caused by blatant cheats discovered through GameSync like 999999BP, 999 of every item, 999999 eggs hatched, carrying unreleased mega stones etc... Very blatant cheats. It's not going to effect you AT ALL if you just gen legal pokemon and make then shiny and BR. That's not how it works.
Damn, Verlisify might be safe then... lmao
