According to Serebii.net, The Pokémon Company has announced that 5,954 Pokémon Sun & Moon players have been banned for “altered save data”. Although normally nothing to worry about for people who do not try to hack their games, there are a number of legitimately obtained Pokémon/move combinations that can erroneously trigger the system. No cases of false positives ending in a complete system ban have been reported, but it is something to keep an eye out for.
Players will know that they have been banned if the error code 090-0212 appears when they try to connect to online functions. It prohibits participation in Rating Battles, competitions, and Global Missions, as well as use of Game Sync.
Oh jeez. Normally I would applaud this, but with the state the hack checks are currently in, I'm concerned https://t.co/espWMIH5lb
