Today I found a message in my Spam folder marked as being from Bob Penikas. Inspecting the original headers revealed the name was fake. The email address of the sender is MWATKINS3342 (at) twc.com.
It was cc'ed to several other addresses, none of which I recognize. If you get something similar with my name on it, I'd guess the spammers are harvesting names from Google Groups again. Stay safe.
