My T's facebook page is more business than personal although she does post pictures of her pets. When I first heard about her, I went to her page to see what she looked like. I sent a FB message asking to be put on her email list and then she friended me. I started seeing her months later and asked about the boundary. She said she's FB friends with most of her clients (she's semi retired so not many) and she likes being able to see what's going on in their lives.

So, I think it really depends on the client, the T. and the situation. Right now it wouldn't bother me at all to see pictures of her and her family. It definitely would have with ex-T so I wouldn't have accepted but her FB page is locked down tight.
