First off, NO, He will not protect you from russian and chinese and saudi trolls. MUSK IS WORKING FOR THEM. LMAO. Have any of you actually taken a look at what's happening on twits?

It's what twit IS now. It's used for kushner smear campaigns, and russian lies. He's part of THE CULT. Full blown truther.
