In reply to C.

You’ll have to loop through every site collection in the web application and run this logic. If you have multiple web applications you’ll have to loop through them too. This link shows looping through all web applications and site collections:

Thanks! But there are multiple ways to Delete Users from SharePoint Site Collection:

1. You can delete users using SharePoint Web Interface
2. Delete users from SharePoint site using PowerShell (Bulk Delete also possible)
3. Remove users from SharePoint programmatically using C#

How about:

$web.SiteUsers.RemoveCollection($web.SiteUsers)

I recently used this to clear up all of my (unnecessary) site collections ACL’s which was wreaking havoc on the crawler… worked like a charm =)
