not really..if it’s public access then questions come up
try doing whatever you want if you own a business
like excluding blacks or making them eat in back
or not making handicapped ramps and johns etc
or hiring dicrimination
and so forth
“it’s their site they can do what they want” is not a reality at the size and public access facebook is
just watch...if they are discriminating on users they will be challenged
like Google, it’s so obvious they stack reference to suit themselves when they can...and folks bitch about it
