YouMint.com spamming. How to unsubscribe?

Every other time i open my mailbox, i anticipate, that there must be some worth emails. But i just cannot believe it that more often i get a spammer(youmint) sending me mails. Here is the screenshot to show how badly they spam me. Damn 15mails in one go.


i was wondering how do i unsubscribe it ? well the process was fuckin lame and either way i had to register myself with them. Can’t we jus sue such dorks, who spam people like anything ? idiots
