account deletion

 account deletion  is a common feature on silos and other services that allows a user to request that their account and information on the service be deleted and closed.

Sometimes these requests come from outside the service itself, like:
 * https://twitter.com/mdvfunes/status/793771622847176704
 * "@withknown Help? I am trying to delete my free site https://mdvfunes.withknown.com Can you help? Fine to delete as is. TY" @mdvfunes November 2, 2016
