Facebook cares so little about scam content I'd regard them as actively complicit in the scams by this stage. Reported a scam as blatant as a Nigerian Prince (crypto product with "guaranteed income" of thousands per week which is "recommended by Martin Lewis" who actually took legal action against them over fake recommendations, according to a fake news website which rips off BBC News web design) to them and the feedback widget later informed me it had been reviewed and found to not be violating their scam policy. And yes, I got more of that type of website in my feed due to "engagement", which I suppose at least wastes advertiser dollars...
