It's all by design, invite selling/trading is a big problem in the tracker world and tracker staff often force people to use their home IP to register for this reason. By having your home IP they can easily ban all your accounts if you are caught breaking some golden rule.
The interview process is not bad, it's just particularly slow in the case of RED. Especially frustating for europeans because most volunteers are in an american timezone and so interviews often happen in the middle of the night (in Europe).
OPS has faster interviews but you want to join RED if you want to climb the tracker ladder, so passing through OPS basically just adds some delay.
Anyway, if you value your anonymity this much, maybe private trackers aren't for you.
