I think you’re wrong. If Facebook defines a community standard, that can be opinion based. But saying someone violated those standards is fact based. It doesn’t matter what the rules are in this case. The rules aren’t the issue. Saying that someone violated those rules is the issue. Whether someone violated the rules or didn’t violate them is a fact. And if they say they violated rules when they didn’t, that’s is an incorrect, fact-based statement which I believe is a case for libel, especially if they say someone broke the rules for things like abusive content.
