According to the paper, the goal is to take 4 minutes on an average PC and that it shall be adjusted according to hardware improvements.

Abusing mail accounts only works if they are mail accounts with crappy hosts. Sane providers will block your account if you start sending 100 mails in 1 minute ;).

The question is if that would still be profitable for spammers. Currently, they just send their spam to millions of addresses hoping that one of them is stupid enough to fall for it. They can do that because it's cheap. But if sending isn't cheap, sending to millions to just get one idiot who falls for it isn't an option anymore.

It would just need to be extended to groups. The protocol is not set in stone.

In any case, I'm not suggesting we all switch to BitMessage. I'm just saying this is going in the right direction.
