If your client or something leaks your IP it happens anyways, if you route it over one node or seven. All the extra energy is just wasted.
Yes. That’s how I see the problem.
And bittorrent puts even more strain on the TOR network the way it works. Probably making it slower for anybody else.
I understand and agree.
In the context of this question, I don’t really cares if the IP changes or if UDP supported or the network degraded. I’m asking a more fundamental one: when the data in the BT protocol contains sensitive information, then why VPN/I2P is acceptable but Tor (or other transport) are not? That sensitive info is still being transmitted. If that Tor blog is true, then no matter what we use, it is still bad for privacy.
