I tried looking at some Yahoo groups to see if there were any likely potential members for my own group. What I found was a cartload of stay-at-home-mom sites, each with thousands of messages that were obviously spam.
Apparently these group spammers think that stay-at-home-moms either want to start some scammy pyramid scheme in their living rooms, or are all looking to sell their bodies online.

Yeah, get in line, pal.
