I'm not sure if you were insinuating that this was the cause of this current ban? Or have just posted something tangentially related with no data or logical chain of reasoning to support it?
I hope the ban is well-considered, but a ban on strangulation and choking in pornography is a good idea. Allowing production or sale of media reinforcing something that dangerous would not have been super smart.
God help you if your pixels aren't the government approved kind though...
And I'm also not surprised that stuff like "CBT" isn't included.
