thanks for the detailed response
what do you mean with:
"Also, another way to get banned is to Game Sync with different region settings.
Originally, my save and 3DS was JP region, but I accidentally Game Sync'd when my device region was set to EU.
That led the save being banned on PGL."
you mean game syncing twice with different region settings or using your savegame and saving on 2 different region settings ? cause my citra (i just checked) is set to united states while my 3ds is in europe. Would i get banned for that ? or just if i synced my 3ds then synced again after changing my region via cfw ?
Edit: also tried the caught all option in pkhex, it still checkmarks the shiny locked pokemon as seen as shiny
