   uu.net (Also known as spew-spew.net in the anti-Spam community.

     There is a great deal of evidence in public archives of spam and reports of interactions with uu.net representatives, that uu.net hosts many spammers and spam support operations. uu.net in fact ranks among the most listed ISPs for this reason at Steve Linford's Spamhaus.org, Sponsor of SBL.
    A post made January 18, 2004, to news.admin.net-abuse.email pointed out that the following:
        On Jan 1, UUNET had 112 SBL listings.
        On Jan 18, UUNET has 123 SBL listings.

Should ISPs Be Knowingly Profiting From Selling Service To Known Spam Gangs?
Press Release by Steve Linford SBL February 4, 2005.
     Since the release of Sobig spammers have released countless virus variants turning millions of private home computers into unwilling spam servers. Crucial in this underground spam world is the stealth bulk spamming software specially written to take control of private computers. Crucial to the distribution are a handful of ISPs knowingly aiding the spam gangs. In this article Spamhaus exposes the author and distributors of the illegal Send Safe proxy hijacking spamware, and exposes one major ISP knowingly hosting the proxy spam gang.
     This for Spamhaus is the crux of the spam problem, because MCI Worldcom not only know very well they are hosting the Send Safe spam operation, MCI's executives know send-safe.com uses the MCI network to sell and distribute the illegal Send Safe proxy hijacking bulk mailer, yet MCI has been providing service to send-safe.com for more than a year.
     MCI executives have refused to stop providing service to these gangs, insisting that the sale and distribution of stealth spamming software is "not against MCI's policy".
     For more than a year MCI have flatly refused to stop send-safe.com and other proxy spam gangs, which has allowed Send Safe to become one of the most sold anonymous proxy hijacking bulk mailers on the spam scene, and has had ever more spammers flocking to MCI.

         Linford Response to Criticism of Press Release.


In September 2004 Savvis, a major ISP, announced that, in response to Steve Linford and Spamhaus.org suggestion to Savvis that Spamhaus was about to blocklist Savvis corporate email servers, Savvis would be begin removing the spammers from their network. Many in the anti-spam community were highly skeptical, especially in light of internal Savvis memos leaked to the Internet which showed Savvis execs had discussed strategies to allow them to keep their spammers and dodge the wrath of being blocklisted by not only Spamhaus, but also SPEWS, which was escalating blocks of Savvis net space. I posted the question below to Steve Linford in the newsgroup news.admin.net-abuse.email, since MCI / uu.net is a major ISP that as a source of spam abuse is far greater than Savvis. Below is Steve's reply as posted with full headers as it my my newserver.

MCI is a much greater problem, it's not a case of a few executives
working against an otherwise anti-spam abuse team that wants to enforce
the AUP, the culture of spam support is deeply engrained in MCI VPs as
well as in the leaders of the abuse department. MCIs abuse department
hates anti-spam organizations as much as the VPs like spam revenue, they
refuse to work with any anti-spam system - doing so would be "giving in
to the anti-spam community" as MCI's abuse chief sees it.
MCI is not a problem anyone can fix overnight or with a few phone calls.
Tackling the MCI spam problem is a multi-pronged approach. As I've said
before, there is no question Spamhaus will escalate listing mci.com
corporate mail relays for knowingly providing spam support to
professional spam gangs, but action from us alone is not going to
eradicate the rot in MCI, therefore we plan action in concert with a
campaign involving press and MCI shareholders.

     uu.net recently suffered quite a bit of public scrutiny for its role in allowing spammers to operate, about the time the state of Virginia was announcing a major lawsuit against one of the reported top 10 spam operations. Seems someone pointed out that uu.net is ranked among the most prolific sources of spam on the Internet by what is probably the most reputable and respected spam email blocklist currently in operation, Steve Linford's Spamhaus.org. Article linked below reports that "...Spamhaus.org, also monitors the world's Internet service providers, the companies that connect people and businesses to the Internet. In that category, Spamhaus lists UUNet as the ISP allowing the most spammers onto its network, based on the Internet addresses they are using:
        Group Lambasts UUNet on Spam
        As reported in the Register online in UK

    One of the first places many in the anti-spam community turn on the web to spot where the spam is coming from is the archive of postings to the usenet NNTP newsgroup news.admin.net-abuse.sightings. This newsgroup exists solely as a place for posting samples of spam email with the original headers as evidence. The archive is maintained by google.com at
        Group: news . admin . net-abuse . sightings
To get an idea of uu.net's role in this problem, go the the URL above, and in the search box enter the text "uu.net" (leave the double quotes!). Right below the search argument text box is a radio button labeled "Search only in news.admin.net-abuse.sightings". Be sure to check it so you search only in this group. Searching on the afternoon of January 2, 2004, I just now got 33,500 hits. Searching on "uu +.net" (this time REMOVE the double quotes), I got more than 38,000 hits. Note that only the tiniest fraction, probably a vanishingly small fraction of 1% of any total single spam run, get posted to this newsgroup. The real numbers of spam emails being sent from uu.net space appears to be pretty monstrous, and growing steadily for the past five six years.
    To get an even better idea of the problem, visit this archived newsgroup:
        Group: news . admin . net-abuse . email
This newsgroup is frequented by many system administrators and technicians active in computing technology and support, and particularly in the fight against spam email. It is also frequented by trolls trying to disrupt the group. The language can get rough. But the bottom line is, a search like that above on the delimited string "uu.net" returns 31,000 posts discussing uu.net and its role in spam support. One can see from the reports over the past five or six years the trend at uu.net towards ignoring complaints and allowing the spammers to flourish, according to claims made by those reporting their attempts to contact uu.net and get uu.net to enforce its terms of service, which actually explicitly forbid the very abuse they appear to be allowing to flourish.

    The following post was made to news.admin.net-abuse.email in a thread discussing the ongoing failure of uu.net/MCI to remove spammers from its network. Linfod, quoted below, runs http://www.spamhaus.org, which hosts the widely used SBL list. In that list uu.net/MCI is prominently featured as being among the top 10 ISP sources of spam or spam support.

From experience I predict that John will find reasons not to deal with 
almost any SBL listing you show him, he'll tell you either that he 
hasn't seen any complaints for Atriks, Marin, etc., or that "some of 
MCI's SBL listings are stale" - but he'll refuse to tell you which ones 
(as that would enable Spamhaus to remove stale MCI spammer records, 
which is a problem when the Abuse Chief's excuse for ignoring spammers 
on his network relies on telling MCI execs that the SBL is inaccurate 
because it lists some stale records Spamhaus doesn't know about ;)
