Yup, "victim" of exactly that here. Had a restaurant with a Facebook + Instagram page, as bunch of people find new places that way apparently, maybe 20-30% of the people we talked to found us via those properties, so hard to just give up even if you disagree, unless you're in a really great location already, which we weren't.
At one point, our Instagram page was banned, no reason provided, and impossible to reach a human, the Facebook page continued working without issues. Must have reached out and "appealed" like 10 times, eventually we gave up and the page seems to remain banned today still.
