- It doesn't make you anonymous. Torrent protocol wasn't designed with anonymity in mind and there are a million ways you're going to leak your actual IP address.
- Tor is a TCP only network.
- While this doesn't give you the anonymity you wanted, it will hurt the network for other users.
and sometimes we do care about successful delivery but need to handle that ourselves so we use UDP to avoid layering delivery verification mechanisms.
