It poses something of a dilemma for those ethically or morally opposed to porn.
I got an airdrop and wasn't sure what to do with them. Burning would just increase the value of everyone else's tokens. Selling would hurt the price, but then I'd be profiting. (I could sell then burn the STEEM, I guess); in the end I staked them and delegated to @noporn4u.
If it's going to happen, and they choose to give me some influence over the content, best that influence is used to penalise any real nasty stuff.
