Works like a charm

This plugin delivers! I tried another one which prevented customer registration from gmail, yahoo etc. but somehow still allowed spammers with “blocked” domains to submit orders for payment verification. With this plugin, those spam orders get stuck as drafts.
Now I just need to find a way to remove those bogus customers, who appear in the woocommerce customer list but not in the wordpress user list, where it would be easy to delete them. A solution to this would be great but is a bit much to ask from a free plugin. 😉
Thanks for this great plugin, Kaleem!
