Great idea that when an IP is blocked by Wordfence on one site it is shared with the other sites in CloudFlare.
QUESTION: In order to share the blocked IP do the sites have to have Wordfence installed?
PROBLEM: Wordfence helps block IPs that hit the login page and attempt to login. However to accomplish its goal it is resource intensive.
SOLUTION: If the CloudFlare Threat Management could share the IPs blocked by Wordfence with sites that do not have either your plugin or Wordfence installed through CloudFlare it would save a lot of valuable resources.
Is any of this possible?
