(Just to be clear, Anthony probably had no idea what was about to
happen.  I sympathise.  It happens.)

I try to carefully avoid treading on Jim Stockford and LX Rudis's 
toes, and respect their administration of this mailing list in any way
they see fit.  Separately from that, however, I do administer this
server as a whole, including the antispam functions of its MTA (SMTP 
daemon) software.  

So, I've just now configured my machine to reject all future mail from

It's very common for these social networking sites to ask new members
whether they wish to invite their "friends" to join as well.  The
software then parses everything in, e.g., the user's GMail or Yahoo Mail 
address book and then mail-bombs everyone with a posting that purports 
to be from the new member, but in fact forges that user's "From:"
header, etc. to simulate being from that person.  LinkedIn has been
guilty of doing that in the past, for example, and probably many others.
I globally ban them when they do.
