The issue isn't banning porn. If you've always had porn banned it's fine.She’s right on that though. No one’s going to compete with Twitter if they don’t allow porn.
Look what happened to Tumblr when it banned porn.
You run into problems by allowing porn for a time THEN banning it.
because porn tends to drive away anyone who isn't coomrotted, then you drive away the coomrots no one is left
