AOL operate transparent proxy servers that filter/monitor and record all HTML data passing from their networks, for many reasons, data mining, advertising etc... It being on the same 24 subnet is a bit strange bit who knows what AOL think.

ISPs that transparently redirect/filter and cache HTTP traffic are always going to be a problem when filtering on IP numbers. I thought about filtering on the HTTP_FORWARDED_FOR headers fromthe caches but that would easily allow a spammer to inject headers and therefore bypass filtering.

All I can suggest is create him an account and mail him the password or decrease the age expiry to under 30 days, that will treat the record at sfs.com as too old and will ignore it.... Or even better, tell him to get his ISP to turn off proxying. A friend owns an ISP and with bandwidth being so cheap compared to the overhead of running caching servers, given the low hits, he turned them all off.
