Same happened with me once. And till date couldnt find out the association and what wrong we did or the association who they say we are associated with!
If you explore Apple apps for utilities/tools like Qr code reader, currency converter, call recorder, vpn, etc. you can find hell lot of similar scammer who are playing it hard for apple to catch.
Happened with me many times. I run various amazon affiliate site. Some times I get expired brandable domain names which are available to buy. When I share any post on fb page from them I get same error and there is no way to fix it. I just have to stop working on those niche sites on fb promotion.
FB sucks sometimes. I can feel this guys frustration.
