With the recent time of CTM Exploiting on NMDC the hublist have stepped up and started to blacklist hubowners that don't take their responsibility and update their software.
The recent hublist to add this blacklist is hubtracker.com this will insure that the most common hublists on Direct Connect has this kinda protection for the future so rouge groups can't exploit others for personal gain as its been done in the past.
Hublists that have implemented blacklist features are
- Dchublist
- Hubtracker
- Hublist.cz
