Is backscatterer.org Safe?

Those claiming this would be extortion or scam are either spammers that try to badmouth UCEPROTECT or they are just too stupid to read what is written on that website. Every IP temporary listed expires FREE OF CHARGE 4 WEEKS AFTER THE LAST ABUSE is seen from an IP. For those that doesn't want to wait for the automatic and free expiration an optionally expedited expressdelisting is offered for a charge. Why should the guys at UCEPROTECT do manual work for lamerz that did not secure their network in first place free of charge? They clearly shouldn't. The lists are available free of charge and it is really annoying that those that gave bad comments expect free support for a free product. They question is why do these guys not offer to work for the project free of charge? If they would do so, then it is unlike that UCEPROTECT would charge for expedited manual delistings. Anyway what UCEPROTECT does is neither a scam nor extortion.

***** does not list for spamming, it lists for poor or stupid configurations that cause harm and is annoying to innocent third parties. People must realize that they have to reject mails to nonexisting users instead of sending bounces afterwards. People must realize that Sender Callouts are irresponsible and selfish behavior harming the poor victims of forgeries. People must realize that Autoresponders should not use the NULL SENDER and that they have to respond ONCE ONLY to already known contacts.

backscatterer.org operates a DNSBL via UCEPROTECT. This is a recognized service, fighting against spam IP's This is an FP on MalwareURL's part and listed for "Suspicious business practices" ? When did the fight against Malware start including generic definitions as this?
