The only thing that could be done is taking advantage of oversights on file-hosting and server-hosting sites, essentially using sites that don't bother to judge the validity of takedown claims. The Zeta Team and company could also try taking down the server for harassment as a last resort, but this is similarly limited since having a good moderation team would be enough to stop any kind of hate speech, harassment, or related. I don't think the copyright-aspect would be a problem since mods are simply free modifications of existing games, and the game itself is also free, currently abandoned/on-hiatus, and lacks the grounds to takedown related material since it unlawfully uses materials from the Sonic The Hedgehog IP. The only two issues would be whether it could be taken down for copyright infringement or if it could be taken down for harassment (the copyright issue would also apply to hosting mod files).
