Hope for the best, expect the worst. They posted an English translation, if anyone cares.
Somehow this made me understand the ban more. I think having unreleased and unavailable pokemon would qualify as one reason, changing gender and OT/TID/SID would be another. As far as genned pokemon, that's really nothing because if you imagine it in the legit world, it's getting them from a trade, or you're just super lucky with the capture and breeding and you were hardcore EV training (which can take less than 30 minutes). I'm curious too about Dittos. In my experience you cannot legally have a 5-6IV Ditto, I tried to chain for one, 700 Ditto chain, not one 5-6IV Ditto appeared. In ORAS I'd say it's possible because the max stars is 3 for DexNav chaining, but I caught 4IV ones. Of course, not just Ditto, any chained pokemon can't be caught at 5-6IV. Just a theory on that.
Incidentally the game I do a bulk of requests and tested out Marshadow for a bit (removed it right after) never set up Game Sync. Really though, the bright side is that it's only GL activities, you can still trade and do free battles and such. If the Ratings Battle and Online Competitions ban bothers you, search for some leagues to sign up on. I hope nobody blames PKHex for this.
