- 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.
I2P is a P2P darknet. on tor the network is run by volenteers (~6000 nodes) while on I2P everyone on the nerwork is a node, and their are no built in exit nodes (in i2p their called outproxies). the official I2P router has a built in torrent client as well. like torrents the more people on i2p the faster the network, while the opposite is true for tor.
