Huh..Reading your post I only hope you will not end up addicted. :) 24/7 is a lot :) When do you sleep?
Ok, so I guess there is no major difference in sites where we post. One way or another our shared and unshared information is used and could be or is abused. More I think about it - I would call it Life. I take every site as a Stage or Podium. You make a speach (post), some people listen, some partly, some not (visit). Some will clap at the end (likes), some will be excited and tell someone about it (shares). Some will be envy, some angry (flags). Some exposures are for free, for some you get a fee for costs and incouragement. What else did we expect? In the end we are only human.
