Most of you might already have them. I don't use any. Only what comes into my company. However a few "one time" aliases that were made for business reasons, I haven't deleted and they are starting to get spam. I just think we might be able to get some nice clean data with some nice new spamtraps for WS. Thoughts? --Chris

Knight-Ridder realcities.com domains whitelisted
by Jeff Chan 18 Oct '04

18 Oct '04

I've whitelisted 100 domains from http://www.realcities.com/, which has a list of city sites run by large U.S. newspaper corporation Knight Ridder. None were blacklisted before. About a dozen were already whitelisted. Most are newspapers. These would be unlikely to be used by professional spammers. http://spamcheck.freeapp.net/whitelists/realcities.sort Jeff C. -- "If it appears in hams, then don't list it."

I'm not one to remove all of these just because I don't have the archived reports. If they are proved to be FPs then hell yeah I will remove those FPs. But to remove over 2k of them just for 2 reported FPs in that file??? --Chris

Took top percentiles of DMOZ and wikipedia domains, some results
by Jeff Chan 17 Oct '04

17 Oct '04

I took the top 50th percentile of the multiple-version-intersected DMOZ domains and matched them with the top 70th percentile of the multiple-version-intersected wikipedia domains: http://spamcheck.freeapp.net/whitelists/dmoz-50thpercentile.srt http://spamcheck.freeapp.net/whitelists/wikipedia-70thpercentile.srt resulting in a list of about 15k domains: http://spamcheck.freeapp.net/whitelists/percentile-wikipedia-dmoz.srt (first column is word counts:) 255838 255838 3955772 dmoz-50thpercentile.srt 28323 28323 402512 wikipedia-70thpercentile.srt 14982 14982 202925 percentile-wikipedia-dmoz.srt that appeared at least two or three times in both data sources. (Percentiles were chosen to give about two or three hits of domains within the same source.) I then matched those 15k against the list of all SURBL domains and got the following hits, all possible FPs: http://spamcheck.freeapp.net/whitelists/percentile-wikipedia-dmoz-blocklist… 0catch.com 1asphost.com 741.com 8bit.co.uk 8m.net anzwers.org arena.ne.jp away.com centralhome.com cheapass.com f2g.net faithweb.com fateback.com fortunecity.de freewebpage.org galeon.com htmlplanet.com i8.com itgo.com iwarp.com kit.net kki.net.pl ledger-enquirer.com nana.co.il online-dictionary.biz p5.org.uk quuxuum.org republika.pl s5.com spaceports.com t35.com telepolis.com transnationale.org up.co.il xiloo.com zip.net zonai.com One additional test I'd like to apply to all these data is to remove any that are listed in SBL, but I haven't coded that up yet. However Ryan Thompson's GetURI does include an SBL check, along with other goodies like domain age, so I fed these into his CGI version, with the results at: http://ry.ca/cgi-bin/geturi.cgi?id=ham-es0EnYAUmBru8HxYCzvQ5x It looks like all are between three and ten years old, aside from: fortunecity.de 2.7 years old 16 NANAS online-dictionary.biz 214 days 0 NANAS nana.co.il 552 days 754 NANAS 1asphost.com 786 days 60 NANAS And only these two had SBL hits: 8bit.co.uk 1796 days 131 NANAS xiloo.com 1667 days 342 NANAS Aside from those two, the rest may be candidates for whitelisting, though I did not check them further. (Note also that GetURI does not count NANAS; I did those few manually. May I ask for some help in checking these? Note that we should still continue to check the DMOZ hits since there are probably some more FPs in there also: http://spamcheck.freeapp.net/whitelists/dmoz-blocklist.summed.txt http://spamcheck.freeapp.net/whitelists/dmoz-blocklist.txt http://spamcheck.freeapp.net/whitelists/dmoz-blocklist.ws 1338 13380 141946 dmoz-blocklist1.summed.txt 1338 1338 20533 dmoz-blocklist1.txt 1173 11730 124298 dmoz-blocklist1.ws Most are in WS.

FP in OB?
by Bill Landry 17 Oct '04

17 Oct '04

Domain, thechildsafetyguide.com, was listed in a Stork Avenue Newsletter (storkavenue.com) and is listed in OB. It's a fairly new domain, but seems legit and the web site looks legit: Registrant: American Family Safety Network Christian Bezick (cbezick(a)bellsouth.net) 2938 Banyan Blvd Circle NW Boca Raton FL,33431 US Tel. +001.5619129617 Creation Date: 24-May-2004 === - No NANAS listings - No SBL listings Bill

Theory about FPs for sites with open subscriptions
by Jeff Chan 16 Oct '04

16 Oct '04

After looking at NANAS hits for FPs, in particular the reporting parties and the destination addresses, I have a theory about some of the FPs. I think some anti-spam zealots may be deliberately subscribing spam traps, either their own or third parties' like Outblaze, to sites with open subscriptions. If so, they're probably doing it to draw attention to the fact that the sites have unconfirmed subscriptions. Or they could be cracker/spammer types trying to use them to poison the spamtrap feeds and therefore diminish the usefulness of data from them. This type of poisoning is a distinct possibility since it would appear that the "spams" (usually subscription newsletters) do appear to come from those sites or senders. I think we should consider the possibilities that either type of people (or even bots) could be adding otherwise legitimate sites to traps this way. (It would be trivially easy to write a spider to subscribe spamtrap or their own address to open subscription sites, and given some of the repeated reporters in NANAS, someone may have done that.) Whatever their reasons, we should not fall into this trap and list otherwise legitimate sites just because they have open subscriptions. Doing so probably diminishes the usefulness of SURBLs by increasing false positives. Comments, Jeff C. -- "If it appears in hams, then don't list it."

Removal of original BE domains from WS.
by Chris Santerre 16 Oct '04

16 Oct '04

We are going to remove the original 3k+ BigEvil domains from WS. We feel there may be too many FPs coming from it, as our methods of checking have gotten 5 million times better then what I used to do alone. So rather then checking them all for FP, we simplt remove. We feel this shouldn't cause any problems, and any domains still being used will be reported to us, and added back in. Does anyone have any objections to this? --Chris (Yankees suck.)
