Maybe we could include Captain_Scar's standard on mudslinging ads: Mudslinging is allowed as long as it doesn't go to far/isn't too personal.
And also, I think people should be allowed to post whatever they want as long as it follows the Imgflip ToS. Which means that people are not allowed to post memes about p*rn or hate towards a certain group of people.
As for NSFW, yes, LGBTQ+ should be allowed as long as it's not actually p*rn or saying things people are not supposed to hear. An example of what should be marked NSFW is... well, take those... cursed comments people make on MSMG. I am a mod of MSMG, but I guess those types of comments are allowed on MSMG.
