I'm happy to report, I have finished the final round of validation, and am currently in the process of removing over 3000 domains that have failed to resolve over a 5 day period. They will of course continue to be monitored, especially given alot of them were associated with rogues, malware and exploits.
Which brings me to the additions, with special thanks to Anthony at MalwareURL for processing and sending me them, I've added 113 sites that are currently hosting Mebroot exploits.
The sites DO NOT LOAD THESE IN A BROWSER!
