When I make an account there's the checkbox that says "allow NSFW content" or something along those lines. I generally don't care, but it would be SUPER helpful to be able to switch it on and off and then refresh. For example - if browsing at work, or while out and about where people might see my screen, I don't wanna click something mindlessly and have tits/porn/blood/etc on my screen. If I could turn it on and off that'd be an awesome safety valve.
