Hi, check out this post by Nux:
Proxy Supply .com - New Proxy Listing Site
You should also be able to block specific domains (eg: proxies4u.com) with the (domain) blacklist in the admin cp.
My proxy lists using the @ proxy script get swampped with .tk domains. Moreover, most of .tk proxies are relayed to abm.me, which user report does not live up to expectations.
How can I stopp any .tk domain proxies for being submitted to my proxy lists including, for instance, proxies4u.com ?
Try adding .tk to the blacklist in the admin panel.
I also blacklist this string:
Submit Your Webmaster Related Sites to the NB Directory
I swear, by my life and my love of it, that I will never live for the sake of another man, nor ask another man to live for mine.
Thanks guys. I have implemented both methods and I have amended Nux'es code to block .tk domains also when submitted using minuscule’s, majuscules and combinations thereof
