I don't like Facebook, either for its personal impacts on my mental well-being or its broader societal impacts. That being said, they have a pretty reasonable policy against mentioning Facebook in ads generally, because they had lots of ads that attempted to seem like official Facebook content ("Facebook releases new game!"), and they allowed the ads subsequently upon appeal
... Which these ads pretty clearly weren't attempting.
I can understand the first line review flagging them via rigid application of "the rules".
What I have trouble understanding is how they apparently don't have a mechanism for handling "high risk" placements, or if they do, it missed ads from a presidential candidate known to be critical of them, exactly the sort of placement such a mechanism, you know, is for.
