Subscribed to BDPA email list?

I woke up this morning with an email saying I had been subscribed to the BDPA
(some sort of business / IT contact group) email list with a note that BDPA
in Phoenix wants to learn more about PLUG.

Then, I had an email from the list with a nice little "plug" for PLUG.

I did not sign up for this list and I was wondering if someone was trolling
the PLUG email list to get addresses for spontaneous sign ups. Anyone else
get signed up without asking?
