This plugin gives you the ability to disable specific user accounts via a profile setting.
Once installed and activated, a checkbox appears on the user profile settings (only for admins). When checked, the user’s account will be disabled and they will be unable to login with the account. If they try to login, they are instantly logged out and redirected to the login page with a message that notifies them their account is disabled.
This can be useful in a few situations.
<ul>
<li>You want freelance writers to still show up in the authors box, but you don’t want them to be able to login.</li>
<li>You have former employees who have authored posts and you don’t want to delete them or reassign their posts to other users, but still need them to show up in the “Authors box.”</li>
<li>You are working on a site for a client who has an account, but do not want him to login and/or make changes during development.</li>
<li>You have a client who has an unpaid invoice.</li>
</ul>

Meet No-Bot Registration, easy to use, superior protection without making it hard for your visitors. Easily blacklist (partial) email addresses and domains so they can no longer register an account.
Create one or more questions and a set of possible answers for them and visitors have to answer your question when they register.
