Emu XL-7 & MP-7 User's Group

(1) Usually the Yahoo groups I belong to have about the same amount of 
spam. However, over the past week or so, there seems to have been an 
increase in the XL-7 group spam.

(2) Just for the fun of it, I checked to see what other posts "Bryant" 
had here before his This-group-is-over-run-by-spam . . . So-join-my-
group" post. I FOUND NONE!!!!

So, the question is, why did someone who evidently did not post 
anything here before suddenly start complaining and trying to get 
others to join his group? (A good follow-up question is why the 
increase in spam in this particular group all of a sudden.)

Just wondering.
