Or "ﻋﺫر أقبح من ﺫنب" in arabic. :D
I got an email this morning - spam, as usual. I usually don't get spam (I keep my email top secret), but this one was some kind of newsletter for Mens Style. I had never signed up for this newsletter, not even any newsletter anyway. Except that this one let you to unsubscribe. I didn't know what was in store.
Just say "We don't want to unsubscribe you, we want to send you more spam", just say the truth. Don't blame your poor old system. But, what about me? I'll just adjust the filters in Thunderbird so they get deleted - much easier.
