[Noisebridge-discuss] possible spambots on NB mailing lists

[Andy Isaacson]

While reviewing our mailing list server, I noticed that we have several
addresses @zeusmail.org subscribed -- one each to many of our lists,
including board at lists and noisebridge-discuss at lists .  The addresses are
<random firstname>.<random lastname>@ .

Discussion on the internets indicates that zeusmail.org is probably some
kind of spam harvesting setup.

Nobody from zeusmail has ever offered any defense, AFAIK.

Should I delete the subscribers and ban zeusmail.org from
lists.noisebridge.net ?  Anybody know more of the backstory here?

For the record, here are subscriber counts for our top 10 lists:

  790   Noisebridge-announce
  560   Noisebridge-discuss
  105   Cyborg
   99   Noisebridge-jobs
   89   Space
   78   EEG
   76   ml
   74   Noisedroid
   67   Build
   50   Security

there are 34 lists in all hosted on lists.noisebridge.net.

We have subscribers on 458 different domains; the top few domains, by
number of distinct addresses subscribed to any NB list, are:

    687 gmail.com
     73 yahoo.com
     26 zeusmail.org
     21 hotmail.com
     13 ethereal.net
      8 googlemail.com
      6 me.com
      5 mit.edu
