You can't really get at the spammers. The e-mail addresses "From" and "Reply to" are not automatically the source of the spam. In fact they are unlikely to be. If you inspect the "Options" of a message it will reveal the server TCP/IP or some such that it was last seen to go through but not an e-mail adress.

I do list e-mail addresses on my website (in hidden remark form) if I can be sure it relates to the spam. That way their fellow spammers might pick it out and spam the spammers.

The latest wheeze concerns sales@LookAtMyCrazyShoes.com (OK spammers - go for it)
I bought from them and made it a condition of sale that they did not junk mail/e-mail/phone and by selling to me they agreed to my terms. So four spams later and no reply from them (the only opt-out is to recieve 4 spams and then unsubscribe)
They invited me to register on their "community" (read Forum just like this) and I did; my name there is IhateSpam and if you go and look you can see what I "shared" with them.
They will get the message. And tire of it before I do.

As it happens I bought a second pair of the same kind of shoes - not from them of course but at Sidmouth - for cash and, you know, I haven't been spammed from that shop! & I didn't gamble on the fit, colur, comfort ...................
