The purpose of a spam filter is to help filter out unwanted email from reaching it's targets. This should be accomplished effectively with 0 false positives. This means without interfering with legitimate emails.
SpamCop kills ants with a sledgehammer. While doing this they are destroying the internet freedoms. Therefore the SPAMMERS WIN, WE LOSE.
I have personally requested my ISP to stop using SpamCop on my accounts, I encourage all those users that have lost emails to do the same. This is the only way to stop the madness.
Since I am an IT professional, I will promise never to allow SpamCop to be used in our enviorment until they stop blocking entire serves for emails of a few users. This just doesn't make sense.
Who do you think you are? And what kind of idiot uses this product?
