Well it's not only about giving out your personal details or links to your twitter or facebook accounts. It's not unreasonable to assume that both of those forums log your IP address and it's very likely if they were asked to do so they would pass that information to legal authorities. So there's a link right there.
This is exactly what DeepSend is (will be) for.
I'm very interested on how deepsend will achieve this, but there is no whitepaper. If you have any links or can give more info on that I would appreciate it. It seems all the promise and all the anonymity will come from DeepSend
White paper will be ready in the nearest future.
