This is one of those things where I agree it needs to be done in this case, but Im not sure it’s going to be possible to do it right to protect anonymity of adults. All it takes is one of these identity brokers to leak which adult went to what site and looked at these genres to destroy any hope of this ever being trusted.

But at the same time, the only way to make this effective at all would be to apply this to internet access worldwide, simultaneously, which is pretty much a no go. You aren’t going to be able to filter every person on the internet. Anyone can VPN around all these roadblocks and view whatever they like.
