I am filled with rage. Have you experienced this nightmare:
You meet someone once . . .or worse, you don’t even meet them, you almost meet over a job thing that doesn’t pan out. . .but they put you on their “email list.” This is like a blog that comes to you. Eventually you work up the nerve to ask to be unsubscribed. And they don’t do it. Some weeks later you ask again. Then they start sending REEEEEEEEEEALY LARGE FILES. In fact, they send you MP3s of copyrighted music. Theoretcially, you could get sued just for answering their dumbass emails. Finally you have to beg to be unsubscribed.
I’ll let you know what happens next.
If they all come from the same address, you can just make a filter that trashes them as soon as they come in.
