/r/opensignups (sadly the lemmy version seems abandoned at the moment).

Monitor that daily if you can. Torrent leech in particular should be opening their doors soon for open registration (they usually do in spring, if not it won’t be long as they do so twice a year anyways). TL is a great starter and honestly many people will never need more. Very easy to maintain on with great free leech on anything over a certain size which ends up meaning all remuxes and most TV show seasons.
