@blablarg18 I can tell you that from my experience with all things Meta (not just FB), they're incredibly biased against anything LGBT.
For example, on the FB side of things, I have reported a number of posts containing very sexually explicit materials for violating the community standards (even since long before AI took over), and as long as it's hetero content, I have had to report the content at least a couple dozen times before they find it violated the standards. I'm not even talking a little nudity that could reasonably be argued as art... I'm talking things like a video clip of straight up hardcore fucking.
By the same token, I've seen things like pictures that show a little bulge, but are otherwise extremely tame by comparison get reported all of ONCE, and they get taken down IMMEDIATELY. For some reason, it seems that if it's hetero, their restrictions are rather relaxed and lacking, but the moment the content is in any way even remotely homoerotic (such as suggestive but otherwise appropriate images of only a male), the content gets stricken quickly without a second thought.
It just baffles my mind how we can see images, videos, etc of a guy and a girl engaging in some sort of sexually explicit activity, and it is deemed to be perfectly fine, and we can even see images or videos that involve only women, and it seems to be perfectly fine, but the moment the image or video depicts only a guy, or it depicts a guy and another guy, it immediately gets shut down as violating their community standards.
Also, the degree of sexuality to the image seems to be wildly inconsistent between straight and gay (especially men only) content. For example, if it's a video of a guy and a girl in the woods where the girl is bent over with her hands against a tree getting raw dogged like no tomorrow, it's perfectly ok and needed to be reported for sexual activity more than two dozen times before finally getting flagged, but a simple image of two fully clothed men out on the street kissing each other, the image got flagged and removed right away.
On the topic of the video and picture I used as an example, I actually took part in a FB wide protest because of how much traction that particular image managed to get. The idea and plot was to get as many people to share it as possible and to share it as widely as possible in protest that it got removed not by AI, but by what was confirmed at the time to be a HUMAN moderator, as they may be able to silence it from the OP, but they cannot silence it if EVERYONE shares it.
So yes... I can say with absolute certainty that especially since FB moderation has been taken over exclusively by AI, they are absolutely biased against gays, and they promote a LOT of anti gay material. The same holds true for anti Christian content. You can bash Christianity as a whole, and you can even share anti Christian memes, and they're viewed as perfectly acceptable, but if you share a picture or a thought that in any way offends Islam, you get put on Metapause.
They operate on a number of outrageous double standards where it's okay for one side to bash another, but as soon as the other side bashes back, they get the book thrown at them. It's also perfectly acceptable if sexually explicit content is hetero, or in a lot of cases, even lesbian, but the moment it's either gay, or it only depicts just a man, it's suddenly a no no. It's kind of disgusting actually because the standard should be the same no matter what side of the fence you're on. Either both sides should be able to do it, or neither side should be able to do it, but that's not how it works from my observation over the years.
