Looks like, after months ignoring the problem, a miracle finally happened at Yahoo / Geocities tonight ...
Yesterday, my list of alive Geocities spammy sites was more than 350 names long.
Tonight it's down to ... 14 Geocities sites ! All others have been shutdown http://nospam.mailpeers.net/alive_spammy.txt
Yee-HAW! :)
Just for fun, here is the RIP list: http://nospam.mailpeers.net/rip_spammy.txt
Definitely fun. :>
Let's hope this continues.
