  • [OT] What's up with comp.editors

    From Stan Brown@21:1/5 to All on Thu Nov 23 10:08:06 2023
    For a couple of weeks now, every time I fire up Gravity it shows
    hundreds or thousands of unread messages in comp.editors. The subject
    lines are mostly question marks, which I assume means non-ISO-8859-1 characters.

    Does anyone know: Is this some sort of weird DDOS attack, or what?

    Yes. "?" can be used to substitute for a character that's not in the
    character set being used.

    Absolutely. You may consider it a denial of service attack. They are in
    a variety of Asian languages, although some are in English, and many of
    the spam articles trigger Google's BASE64 encoding. A few are encoded in Quoted-Printable. Yes, they do tend to use encoded-word on Subject.

    For several months, there have been massive spam attacks through Google
    Groups into various newsgroups. Ray and several others have been issuing
    NoCeMs as a spam countermeasure. I thought individual.net was processing
    them. If not, you could request it.

    Note that volunteers are analyzing the spam and adapting as the spammers
    are adapting to the countermeasures. Therefore, even with NoCeMs being processed, you'll still see spam that hasn't yet been countered.

    Most likely spam from Google Groups.

    Can you implement a filter ruleset on your client?

    The Usenet Improvement Project website has information on filtering
    Google Groups posts in the OP's client, Gravity. <http://twovoyagers.com/improve-usenet.org/filters_ex3.html>

    Thanks for the info, Adam. That would explain why today Gravity said
    there were several thousand new ones on the server, but only a dozen
    or so appeared when I opened the newsgroup. I don't have a rule to
    kill Google Groups postings, because some worthwhile posters use GG;
    but I do have a rule to kill posts with garbage characters in the
    subject. That would be why the dozen or so had already been marked as
    read.
