I'm also guilty. I know whether my Ts and dietitian have twitter, facebook, or pinterest, and I accidentally found my group T's recent wedding pics online (this surprised me). I was just looking up their names to find info on them professionally and lots of other stuff pops up due to their uncommon names. The wedding pics even confirmed that she's the religion I suspected she was.

I don't mention any of this, because I'm not a stalker. I don't go to their houses or have their personal numbers, I don't check the sites I know they have, I don't want to actually infringe on their life in any way. I'm only accessing what is publicly available and know that anything beyond the professional therapist-client relationship is off-limits for their good and mine.
