The name of the forum - it is not petite women or whatever, it's literally 'fauxbait'
A below comment from Doctorcrimson who seem to have gotten a very different impression than you from the same community

Do explain how banning porn groups forms echochambers tho, never heard that one before

Not specifically porn groups, I said not to be too banhammer happy. They were basically accused of being borderline pedophiles so everyone should block them. But I just can't see any evidence of that, it's literally the main sidebar rule that age verification is required and it's in every post I looked at as the rules required. And I didn't see anyone doing anything other than the usual creepy comments about how they want to fuck her that you will see on literally any porn forum.

That sort of jump to conclusions ban first mentality is what starts to lead to Echo chambers. Not from Banning porn specifically but just the mindset of ban first don't verify
