I just found a link to a Blurtit facebook page and one of my questions was on it. I loathe Facebook and I'm very careful not to have anything of mine on there. I was unaware that my questions might be posted to facebook. How can I get it removed?
You can ask the site management, but realistically, anything you post on the internet can legally be used just about anywhere else.
Long story short: You're S.O.L.
