I recently tried PeerBlocker and was suprised to find I could not access Comodo.com using the simple level 1 blacklist from BlueTack. :o
Evidently it’s either a misfit, or Comodo is involved in anti-p2p and government funding?
Companies or organizations who are clearly involved with trying to stop filesharing.
Companies which anti-p2p activity has been seen from.
[b]Companies that produce or have a strong financial interest in copyrighted material.[/b]
Government ranges or companies that have a strong financial interest in doing work for governments.
Legal industry ranges.
IPs or ranges of ISPs from which anti-p2p activity has been observed.
I suspect that Comodo is blocked for the reason I’ve highlighted above. As a certification authority, I believe they fit the bill.
