How to Mark a User as a Spammer?

Marking a user as a spammer in WordPress MU is rather straightfoward. The steps to do this are below.

1. Login as an admin user
2. Go to your Contol Panel
3. Choose Site Admin
4. Choose Users
5. Check the box beside the user(s) you want to mark as spammers – As a reminder here do not hit next or move to another page. You can only mark users from the current list
6. Select the Mark as Spammers box below the user list
7. Click the Apply Changes button
