that's actually jesus punishing you for sinningnot exactly to do with layout but pornhub has this annoying habit of opening up a new tab for adverts with every click you make on the website. And they do this clever thing where sometimes the original tab that you were on starts loading up the ad and the new tab loads up the page you actually want to go to (I imagine to bypass/confuse all manner of pop-up blockers)...so you always have to check before instinctively closing a tab lest you fuck up.
getting accidentally stuck on a shady online-poker website is a great boner-killer.
