“WooCommerce Email Validation” is an extension for WooCommerce that adds a ‘confirm email address’ field to the checkout page as a required field. This will ensure that your customers will enter a correct email address, making managing your orders far easier and more reliable. If a customer’s email address does not match up then they will receive a standard validation error on the checkout page informing them that they need to make sure that their email addresses are the same.
This extension is WooCommerce 3.x compatible and supports localisation using WPML. It has built-in translations for English, German, Spanish, Dutch, Swedish, Japanese, Polish, Brazilian Portuguese, Hungarian and Serbian.

Simple Trackback Validation Plugin performs a simple but very effective test on all incoming trackbacks in order to stop trackback spam. Now with topsy.com blocker.
How it works:
When a trackback is received, this plugin
<ol>
<li>
checks for topsy.com trackbacks and marks this as spam.
</li>
<li>
checks if the IP address of the trackback sender is equal to the IP address of the webserver the trackback URL is referring to. This reveals almost every spam trackback (more than 99%) since spammers do usually use bots which are not running on the machine of their customers.
</li>
<li>
retrieves the web page located at the URL included in the trackback. If the page doesn’t a link to your blog, the trackback is considered to be spam. Since most trackback spammers do not set up custom web pages linking to the blogs they attack, this simple test will quickly reveal illegitimate trackbacks. Also, bloggers can be stopped abusing trackback by sending trackbacks with their blog software or webservices without having a link to the post.
</li>
</ol>
There are several options available and you also can enable logging to get all actions, which are performed by the plugin, logged. Also, you can select how to treat spam trackbacks (do not save in the database or mark as spam or place into moderation) and several other stuff.
