The problem I am having is the ability to fight spammers who add
unsubscribe from this mail list by clicking here into their spam emails. Turns out I am not the only one to suffer from this, Gmail doesn't filter these mails.
I made a simple test case, created an email on Gmail and contacted one of the spammers asking him to add my address to his list (such a bad idea :P) and Google thought that I am already subscribed to that list and put it in my inbox. These kind of spammers use many accounts to send their spam which make this job much harder.
How do I report these spammers, and block them in Gmail or mail mail servers?
What is the fastest way to do that?
