I've made a site where users can select subtitles to put over top of films (old and new) that are uploaded to Youtube, even when there are no subtitles on the original Youtube video. The subtitle files are stored on the site (ranging from 10-60kb each). My question is, would I be able to host my site on HelioHost, or would this concept break the "no copyrighted material" rule in the ToS? I'm not sure, myself.
