Security Insight

Stop fake or misused emails in your comment section. 
This plugin prevents spam and ensures valid email ownership by requiring users to confirm their email address before a comment is submitted.
When a user leaves a comment, they’ll receive a one-time confirmation link by email. Their comment won’t appear until they click the link — no accounts, no passwords and no friction for real users.
Why Use It? 
– Improves trust and deliverability. 
– Cuts down on abuse, spam and bot activity. 
– Ensures email addresses actually belong to the commenter. 
– Comments from verified users go straight to approved or pending in the future.

Since WordPress 4.4, the Add New User process selectively allows an email to be sent to the new user about their account. The default selection is to send an email when the account is created/added.
In some circumstances, an admin might wish to set up one or more accounts in advance – perhaps for testing purposes – and only notify the users later, once everything is ready. However, it’s easy to send a notification message when you didn’t mean to, if you forget to change the default notification setting.
This simple plugin reverses the default behaviour so an email is NOT sent by default, as follows:
<ol>
<li>
In standard WordPress, the tickbox “Send User Notifiction” is ticked by default (so a message is sent). The plugin changes this to unticked by default (so a message is NOT sent).
</li>
<li>
In WordPress Multisite, the tickbox “Skip Confirmation Email” is unticked by default (so a message is sent.) The plugin changes this to ticked by default (so a message is NOT sent.)
</li>
</ol>
NOTE TO MULTISITE SUPER-ADMINS: Adding a user from the Network Admin / Add User screen (rather than from a particular sub-site’s Add User screen) will always send a notification.

Skip Confirmation On

Changes the tickbox default to NOT send an email to a new user when adding them to a WordPress or WordPress Multisite website.
