Spam to NANOG-specific email addresses?

[Jima <nanog () jima us>]

Esteemed colleagues,

 Did anyone else get a Twitter invite from @washsuntimes to their 
NANOG-use-only email addresses?  Granted, mine was with my old one, but 
it was still very much specific to this list.  Maybe not the best place 
to harvest addresses.
