Reply to "People Posting Photos of Other Cookie Designers' Work to Your Facebook Page as "Suggestions"?"

I'd be as uncomfortable as you are with this behavior. If she's not a great personal friend, I would consider banning her from your business page if she persists despite you telling her over and over. But, if that would damage a relationship that is important to you for other reasons, then I'd just quietly continue to remind her and tell her you are removing her photos each time you do. Hopefully, she'll eventually get the message, especially if you let her know she is making added work for you in removing her posts. You could disable all visitor posts, but then no one else will be able to post to your page either, and that may not be something you want to do on account of one person's misbehavior. I have disabled all visitor posts on my page only because I was getting a rash of sexually explicit and other unacceptable spam-type comments every time I posted.
