Wazoo Posted November 9, 2004 Share Posted November 9, 2004 Per Ellen's request (and Julian's coding); There have been a few small changes to the blocklist; the one that will most affect people is this: IPs now delist after 24 hours if there are no reports rather than 48 hours. IPs with 2 reports will delist in 12 hours. This appears to be working out well but, of course, if we think that it is being abused in some way then the listing and delisting criteria may change. Ellen SpamCop f/ups to spamcop; if someone would propagate this to the forums I would appreciate it. Link to comment Share on other sites More sharing options...

Combined with the 72 hour to 48 > hour reporting limit, it sounds to me like SC is giving spammers a free pass > every 2 days........assuming they are on a black/greyhat ISP. We don't think this will assist spammers but we do think that it assists people who have been compromised and who have found the problem and fixed it. An IP can delist and then immediately relist of course and I have seen some that have delisted and rapidly relisted. For spammers who are just pounding away I suspect that they never have 24 hours without a report and if they do and start back up then they get relisted. Remember we have a lot of spamtrap traffic in addition to the user reports. Again if it looks like this is counter productive then we can always go back to a longer list period. Decreasing the reporting window was to make the reports that get sent more timely. If an ISP is not going to do anything about a spammer then it doesn't matter how old the reports are or how fresh for that matter but if they are then they certainly know about the problem within the first 48 hours of the spammer sending and more likely within the first 24 hours or even fewer hours. As I said, we looked at the data and decided this made sense. If it turns out to not make sense we will undo it or do something else.
