We're running our company business page. Sometimes, one of us wants to share something with just the colleagues, so when posting he/she selects Custom as a post audience, and then selects business page name. This seems to limit the audience to whoever has selected "Works At" [our business page] in their profile. This is all fine.
However, I cannot find a way to moderate this in any way. We have ex-employees still carrying that tag, and anyone else could also improperly set it.
How can we remove/administer/see who has set "Works At" to our page?
