Sega's normally pretty good about stuff like this... remember SegaSonic.Net? The one that hosted sites which hosted ROMs and even a recording of the JP Sonic OVA? Sega ended up paying SSNTails for the domain. And then there's Sonic Stuff, which was hosting ROMs and MP3s of OSTs. What did Sega complain about? Only that they were hosting the Sonic Advance 3 beta, of which there were rumors at the time implying that it was the final version, despite all of the bugs. Sega left the rest of Sonic Stuff alone.
