This blacklist operates in a deceptive manner. It lists ranges of IP addresses without providing clear reasons for the listings. As expected, you can only be delisted if you pay them. Contacting them is nearly impossible, as their form requires a code that is not provided, and they threaten longer listings if you seek to contest an incorrect listing. This is extortion and illegal. Even if you pay (which I advise against), your IP could be listed again at any time. I wish service providers would ignore this dubious blacklist.
