READ THE TERMS! lol Seriously, even if they are ridiculously long and complicated (which I assume is so no one will want to read them) - at least look at them. I don't have to read all of it before I find something unacceptable most of the time.
Take your photos off until you do (or at least don't put any more on there!). You see already what happens - and fast! At least that's my suggestion, delete them and figure out what to post before you put anything else on there.
And it's publicly viewable depending on how you have your page set; even if you don't have it set public with all the sharing that happens you're sending your photos 'out there' and have no idea who may share them or who might see them or where they may end up. I personally would not post any boudoir on there. Better I think to post select photos only on there and a link to your own website.
For clients you can provide copies for social media use that are an appropriate size. Usually photographers (here anyway) provide client photos without a watermark but that's the problem with providing large digital files instead of prints and images for social media use - if you're giving them large digital files they can edit easily I suppose they will. Make it easy for them to use the copy that's for social media use so they'll be more likely to use it.
This is why I don't do people... lol I don't know if any info. from
American Society of Media Photographers or maybe PPA would be relevant for you but might be worth a look. ASMP did a webinar on social media, they're free, don't have to be a member, just sign up (don't know if they'll do any more on that topic).
I rarely post a photo on FB (and I only have about 20 friends and 20 acquaintances and they're all people I know!) and if I do it's a downsized crappy copy of an old picture that was just for fun, that has a watermark and something about unauthorized use etc. Then after a day or two (or a few) I delete them.
