It is powerful in fighting spam. If you use SpamCop to your advantage, you will, indeed, be successful in eliminating spam. However, the SCBL has disadvantages. It is not a perfect innovation and therefore has its own defects.
There is a big risk that as you block email from various spammers using the SCBL, the messages from those whom you want to get email from can also be blocked.
It does not have a mind on its own, thus, it can't identify which messages are wanted and which are hated.
The SCBL is a blocking list of various IP addresses that have been reported to be sending spam to those who have installed SpamCop. |
