But I can’t seem to replicate it. That guy seem to think it was this user http://codepen.io/LEO01/ but again I can’t find a pen that causes an actual redirect. It’s certainly not a hack, but we do of course allow users to run arbitrary code so stuff like redirects can slip through if we don’t stay on top of stuff like that. So if you can find the Pen and replicate the redirect, definitely let me know.
Today my friend failed to load codepen too. Instead he was redirected here 18.104.22.168 (SecondLife MMO).. No matter was it a direct pen-link, or a home page link, or a google search result for “codepen”..
