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).
