A unique anti-spam solution to help you fight spam in registration, comments, forms (Contact Form 7). 
When the user comment or using contact form 7 his comments or message will not sent or be visible until 
the user will press a unique link sent to him when he submited his message.
<h4>For Example:</h4>
Think like this i’m a spammer registering to your site, after register to your site i see a message about 
the need to activate my account, if i used fake email address this address will be blocked because it’s never 
activated, if i used a real address i activated my account with success ! 
Now i would like to change my email address so i can spam without getting any messages from your site but oops 
i can’t change my email address because the plugin blocking it ! 
Ok let’s try my luck and start spam in the commnets, posting my first comment and getting a message: 
“to see the comment you must approve your comment by pressing the link in your email address”.
I think you got the idea but what would happen if i will not press it the email and the ip address will be blocked because no one press the link, if i did press the link in the second on the third time YOU as site admin can block 
his ip and email address manually in the plugin options.

If you run a WordPress or BuddyPress installation, you probably know that some of the biggest administrative headaches come from the activation process. Activation emails may be caught by spam filters, deleted unwillingly, or simply not understood. Yet WordPress itself has no UI for viewing and managing unactivated members.
Unconfirmed creates a Dashboard panel under the Users menu (Network Admin > Users on Multisite) that shows a list of unactivated user registrations. For each registration, you have the option of resending the original activation email, or manually activating the user.
Note that the plugin works for the following configurations: 
1. Multisite, with or without BuddyPress 
2. Single site, with BuddyPress used for user registration
There is currently no support for single-site WP registration without BuddyPress.

Unconfirmed

Googled for "wordpress cancel pending users", this plugin can up as one of the top results, so installed, activated, and achieved exactly what I needed, inside of about 30 seconds. Literally perfect.

Did exactly what I needed

Nice, simple little plugin that makes it easy to get a user up and running when you have, for example, email deliverability issues.

Works as advertised

Thank you for this plugin. Not sure why such a feature isn't already part of Core, as it's very useful when managing a multisite!

This should be part of WP Core!
