Most useful unique website thing rarbg had by far was full mediainfo listing for every single upload on site. You could immediately tell what you were getting and even dead torrents became useful by virtue of retaining chapter data that could be applied to another release.
Also, call me skeptical but IMO without access to scene FTP’s or week-1 access to (and automation on a large scale of re-uploading from) cabal trackers like BTN to get the good content from your site frankly risks ending up just another mirror among many others like lime torrents for existing public net and low hanging private tracker fruit. (If you have mediainfo for all files that adds a lot of value though)
IMO the real need left by rarbg is not for more re-hosting of content many others have but for publishing web-dl’s others don’t have, not of just new series (which everyone does as ep’s drop) but older movies and older series without other good 1080p or 4k releases available. Even today I see many old TV series the only HD releases available are old rarbg packs and this includes across multiple of the biggest PT’s.
Of course I wish anyone willing to run a big general tracker luck (assuming they’re honest and intent isn’t to distribute malware ofc).
