So, in that case, I wonder what would happen if someone just flooded the internet with modified save files for free. Remove the money incentive and just publish thousands of uploads around the web from outside Japan.
If the sites are hosted in Japan, then they could be taken down by Japanese courts. If the sites are hosted outside Japan, it's very likely nothing will happen.
Trying to profit off someone else's IP is the problematic part(as with any fake brand products). They don't go after every ad-supported save file repositories of curious interest.
