Some of those who joined added their friends. If those friends are already friends with EX-JW's who are active on EX-JW sites are they not already putting themselves at risk?
cantleave, it is my understanding from Juan, that if you were in a FB group, someone else in that same group could add your without you knowing to the AAWA group. They didn't have to be a FB "friend."
Again, people were outed. That is a bad thing. I was added without my choosing, to me that is a bad thing and a good thing for AAWA.
