I've never had one that required an interview, but my primary private tracker requires you to log into the webpage not on a VPN. They still suggest heavily that any torrenting is done on a VPN though.
If the owners of the site are competent, they're gonna hash your IP for their logs and not store the actual IP. Hashing is a one-way process, they won't be able to reconstruct your IP from it. If they're storing your raw IP, probably stay away. (Honestly, you can't do nearly as much damage with an IP address as people think, but it'd be a hint to way worse security practices elsewhere)
