Seems to come in waves on AOL, I'll get a bad week then very quiet for 10 days...the spam is from sources listed on the SPEWS blocklist but then noticeably stops...maybe AOL using SPEWS or similar but always playing catchup like most ISP's.
I report the spam each and everytime as hate to say it if u dont then you cant expect AOL/yr ISP to know about it and block it can you
