[Wimble]

I found this site the other day: http://kinksecrets.com/kdice/index.html

Very risky! It's basically like many of the extreme blackmail dice dares on GetDare, except here you upload your pics and answers directly to the site. They stay there until whatever time you get in your final roll has elapsed.

If you chicken out and don't reach the final roll then it just stays up forever. This becomes a risk if you've shared the link with anyone. But there's no gallery of previously completed or abandoned dares - it's only visible to those with the link.
Oh, and whoever runs the website, quite possibly. And maybe Google. So proceed at your own risk!
