water cooler :: Greeting card spam

Does anyone know where the "xxxx has sent you a greeting card" spam originates?
.
I logged into this forum yesterday and this morning I have 6 spam "greeting cards".

I am not selling your email addresses to spammers if that's what you are asking. I'm hoping this is a coincidence.

I do a login almost daily in this forum and never(never) received greeting cards like those.
Certainly this is a coincidence.

I wasn't trying to make any connection.... I keep pretty close track of my Inet activity .... the sudden appearance of similar types of spam raises a flag...
None of the so-called "greetings" saw the light of day on my system ..
Just wondering !!!
