I assume there are abuses of server names by companies that call them as valid sources for the blacklist (spam server lists).
1. As I understand they receive money to be delisted like:
2. Example: they receive money from ads placed from web companies. This companies abuse SPAM lists as advertising.
3. I'm not sure as some valid website like to fight against spam messages, but there are financial consequences if USA servers or EU servers are blocked with black lists. It is not fair and legal.
4. Their domains do not talk about owners of this domains.
Interesting issue is as they use valid extension .ORG and .NET but server based SPAM checkers use old way to check SPAM messages like SPAMcop which is the most used valid domain.
Is this correct?
