I would challenge that censoring sex is perfectly reasonable and nobody cares. I hear adult models bitching all the time that their content keeps getting taken down even when they try not to violate any TOS. It's really hard for them to promote themselves and make a living -- especially now with SESTA and FOSTA. I can understand filtering and flagging something as NSFW or something like that but to remove it altogether is a bit much for such a public platform. I think Twitter takes a good approach to it. It is flagged so you can avoid it but you can opt in if you want it.
