Programatically delete a user in Orchard - orchardcms

Question

I am not an Orchard guru. I am a desktop apps guy with a lot of responsibilities that inherited a big blob of Orchard code and have been tasked with a few maintenance tools. I have tried googling the interwebs to no avail, so I am turning to Stack in a desperate attempt that someone has the easy button...
Basically (and this is an over-simplified use case) - we frequently have users that signup with a mistyped email address or forget their account information within a day or signup again but fat finger the password and then signup a third time, etc...
I have a maintenance console that allows an administrator to 'locate' data (in our own non-orchard sql tables) associated with the first or second accounts (in my example) and re-associate that data with the third 'current/correct' account.
At the conclusion of this re-mapping, I would like to programmatically clean-up (read: delete) the Orchard logins for the first two accounts which are now officially kruft.
I found some information on Stack here that talks about Orchard user accounts:
Users are content types and Orchard creates content items for each
user. When you create a new user Orchard adds records to
xxx_Orchard_Users_UserPartRecord,
xxx_Orchard_Framework_ContentItemRecord,
xxx_Orchard_Framework_ContentItemVersionRecord and
xxx_Orchard_Roles_UserRolesPartRecord if you linked any roles to the
user.
The xxx_Orchard_Framework_ContentItemVersionRecord table keeps track
of the version number and whether or not a content item is published
or not and which version of the published content item is the latest.
When you delete the user Orchard does not delete the records from the
tables, but simply creates a new version record and sets Published and
Latest columns to 0 for the new version and the old version. Because
there is no published and latest version the content item does not
show up on the list of users.
I understand this conceptually, but I can't believe to delete a user that I would be required to delete the records from each of these 'private' tables in orchard. Instead, I expect there is a class/method/technique for deleting the Content Type or Part or Record or whatever (I'm still haven't quite got Orchard object naming straight in my head).
Can anyone share an example of deleting a user in code (by Id or Username or Email)? Or point me at the relevant documentation? I'm fumbling around like a fish outta water here...
As always, thanks in advance!

Answer 1

So as you say, within Orchard most deletes from the UI are soft deletes, keeping all the data and setting a flag in the database to say this guy is deleted. To do this programmatically, where _contentManager is an instance of IContentManager.
var userItem = _contentManager.Get<IUser>(userId);
_contentManager.Remove(userItem);
To do a hard delete, which will delete the item record, all item version records and all content part records (titlepart, userpart etc.)
var userItem = _contentManager.Get<IUser>(userId);
_contentManager.Destroy(userItem);
This was added to orchard in version 1.9.
