There's close to 0% chance of getting banned for accessing the game from a foreign country. It's probably not that hard to weed out the gaijins from the non-gaijins if they tried.

Anyway, it should be good enough if you've the "Force Cookie Hack" option checked in your KC3 setting to allow you to browse dmm. Then it's up to you whether to play via API or DMM.
