As discussed in #174, this is now the "silence" admin feature. See that PR for remaining items needed to resolve this.

Addressed in writefreely#189.

PR for writefreely is up including CLI flags, next is to add things like federated deletes for all collections including default (i.e. username) and and posts if they are being deleted as well.

status update

Looks like this function also already exists in writefreely under *datastore, but is still out of date and needs modification.

Note: implementation details are out of date and only apply to Write.as. For implementation in WriteFreely, refer to [deleteAccount()](https://phabricator.write.as/diffusion/W/browse/master/database.go$2674) func in rW.

{T706} solves our immediate needs for #write.as_for_teams, so we'll do that first. Then we can look at addressing this.
