Well, I was just thinking the same, but amazingly the list that nend posted is 99% the same as mine... I had only 10-15 additional IPs, but always from the same networks... Is it coincidence? I think it will be rare occasion to have another IPs except these... For users (like me) that do not have enough skills to run TorDNSEL service or was unable to install the suggested hacks like Login with Email or blocking... this will be the last hope, just to block IPs from htaccess or iptables, right?
