Don’t bother. Private trackers suck. You have to maintain a certain ratio, which is much harder to do than you think when every single popular file has no leechers cause everyone’s doing the same thing. So more often than not you have to download a bunch of random BS that no one wants and seed it forever just to build up a high enough ratio to finally download what you actually want.
If you’re going to pay for torrents, save yourself the hassle and just sign up for Real-Debrid instead. You get direct downloads at up to 1Gbps, so it’s just as fast as a private tracker, and there’s no worrying about seeding since all the most popular torrents in the world are stored directly on their servers. (You can also easily add torrents that aren’t already on Debrid, in which case it behaves like a seedbox.) ~$17.50 for 6 months.
