Yup. I don't mind as much in closed groups but Public groups are
   very public. FB decides via their algorithms what to show to
   anybody who is a friend or friend-of-a-friend (FOAF) based upon
   some growingly clever techniques (I'm finally impressed by them)
   - and so I'm a 'tad' more careful about image. Not *too* much
   mind you. I gave up on online privacy back in '02 when Google
   gained Usenet and said, "HEY EVERYBODY LOOK WHAT THEY WERE
   TALKING ABOUT IN THE EARLY 1990s!" Ugh. Some crap 18/19 yr old
   Ken posted had to be deleted by 30 yr old Ken. Now I'm 43 going
   on 44. Thankfully it was only about a dozen Kills I had to
   request. Anyway, yeah. I learned to just keep some thoughts to
   myself. = yeah - it's for that reason I don't mind seeing ppl
   using fake accts here and there. It gets abused of course -
   that's annoying - but for some people it's a way to get around
   the "Real Name" thing and all the connections that you drag
   around with you. I don't use anon accts myself 'cause I got over
   any need to "say everything" long ago. But, some ppl find it
   valuable. =
