Just opened Vine... Full porn

I opened the Vine app just now and it is nothing but clip after clip of porn. This is very troubling because I have been showing the app to coworkers the last couple days. Fortunately, I was not demoing the app in this instance. This is unacceptable. Sure, people will use this app for porn, but to have it loaded on the main screen when you start the app is terrible and will probably result in it getting temporarily pulled from the App Store.

This is probably the result of hackers, so twitter ought to just take it offline until they can get the service locked down. Has anybody else experienced this today?
