The SPFBL.net is not a criminal enterprise. It's just another competitor of you and it's welcome considering the criminal attitudes of companies like Spamcop and Netcraft.

The SPFBL.net aims to be a collaborative system to combat spam. A cooperative system: users share alerts against spammers through a reputation mechanism. I hope they succeed because the Brazilian population is tired of being the victim of damn ISPs. But take care, consider this with a grain of salt, after all they are... Brazilians.

Hello,

Can anyone share any experiences with:  http://spfbl.net/en/dnsbl/

It seems that they list servers that are used to file complaints with
Spamcop and other blacklists - as "spam" servers...

They do not de-list these servers, ever, and it seems like a criminal
enterprise or services designed to 'punish' or list complainants or
victims? 

there are of course other 'fake' / non maintained and worthless
blacklists, like abuse-att.net etc etc. but these generally do not go
out of their way to punish victims...

What is the best way to fight criminal enterprises that enter data
streams and 'hide' / market etc as ethical service providers?

Andre
