that's not the official account still, and running the wallet doesn't mean a premine necessarily. i mean, they DO have to test the wallet to make sure it connects to the network after all. i think they admitted to a premine previously though, but it's not supposed to be big. i have no problems with a minor premine personally. making a coin takes effort after all, and it costs money to set up a network infrastructure. just depends how big the premine is...
