The emailleaktest site linked by OP is a word for word down to the privacy policy blatant copy of http://emailipleak.com which we made. Not sure why this is hacker news front page worthy.
And send GoDaddy a DMCA takedown notice for this copycat site. It was just registered a few days ago and given that they shamelessly ripped your content off, I'd have serious reservations about trusting them with my data.
