Are not spam reports sent anonymously?
I had a call earlier from a person complaining that I had him blacklisted.
His email message was indeed reported to spamcop and yet a few hours later this guy contacted me!
How did he know who 'grassed him up'?
Isn't this defeating the object of spam reporting? How best to harvest valid email addresses than to send out spam, wait for the blacklisted reports and see who squealed to the spamcops.
