Private trackers that allow Tor

• OppaiTime explicitly allows it ("You can use Tor... we do not care. The only caveat to this is that if you use an IP address that some other OT account also uses, it may prompt a duplicate account investigation. It probably won't, but if it does, we will check to see what the IP belongs to before we think about holding it against you... but no action will be taken until a human confirms that duping is absolutely what's going on. If you're not duping, you don't need to worry about it").
• IPT explicitly allows Tor Browser as one free way (of many) to bypass censorship of their site; others include Psiphon, Cloudflare Warp and a .bit domain.
• Demonoid has an onion v3 address, it is http://iwjtlm6vtd5gtl4hfiusc6d7zmql6...nriy7yd.onion/.
• RED allows the use of any and all anonymizing services to download and seed torrents, but not to browse the site. Tor should not be used for tunneling P2P traffic in any case.
