Dear ComBOTS

Today I received a nice newsletter from Combots:

Dear ComBOTS friends,

In this newsletter we're once again delighted to bring you all the latest news from the ComBOTS world.

....

Unlike ComBOTS I was not very delighted receiving this newsletter as I had unregistered myself a couple of weeks ago for the 3rd time!!! I haven't really checked out their wonderful, groundbreaking new instant messenger, but if they can't even stop sending me newsletters I don't even wanna know what would happen to my instant messages.

So please ComBOTS stop sending me f***ing newsletters!
