Email Addresses Receiving Spam

I give out different email addresses to different providers, mailing-lists and websites to see how what gets leaked. It’s partly a check on privacy policies, and partly a way to ensure I can blacklist emails efficiently. I’ve run various schemes with email addresses on my domain maz.nu over the last eleven years. Here is what I have found.

Registered with IANA for a private enterprise number for OIDs, iana is listed on a public website. It gets a lot of junk. There are a number of variations, however, which also receive spam:

3aiana
3eiana
iana
ianan
ianann
ianar

I see the appending of “n” and “nn” and prepending of “3a”, “3e”, et cetera for other addresses in my block list. “3a” and “3e” might correspond to ASCII characters “:” and “>”. The “n”s and “r” might be C-style “\n” and “\r”.

Listed somewhere on SourceForge, kinterbasdb was an address I used for a software project I contributed to back in 2001/2002.

kinterbasdb
kinterbasdbd
kinterbasdbdd
kinterbasdbi

I’m not sure how these corruptions could have occurred, but they’re clearly on some spammers’ databases now.

And here are a list which don’t fit any of my schemes for addressing but have received a huge amount of spam in their time:

4m3yseg
5ln
amymc-rus
begoxo
cuoya
hy953j0tr
ln4kc6xvpt
nuxero-geoy
pmb
wmware2003

A million monkeys must have generated these and had them included into the spammers’ lists.
