Id X and Y.

X was created as an ad-free alternative to existing social networks, such as Facebook and Twitter. 

The X web site was launched on March 18, 2014, complete with a manifesto that claimed to distinguish it from social networks such as Facebook. The site promised it would never sell user data, proclaiming that "You Are Not A Product".

The social network service officially launched on April 3, although membership registration was only by invitation.

X gained added attention in September 2014, when numerous members of the Y  community left Facebook following the controversial enforcement of its real-name policy, thought to be intended to exclude drag queens in San Francisco.

At its peak, the social network was processing more than 30,000 signup requests an hour.

It is estimated that 20% of sign ups remain active on the site one week after registration
