AutoSSL - Prevent DDoS attack using AutoSSL

Hello.

AutoSSL can be used for DDoS attack.

Please add futures which check only local domain names which are parked on server and have correct DNS settings.

Example:

If cPanel users add 1000 domains domain which are on 3rd server. AutoSSL will sending and sending requests to 3rd server without checking if these 1000 domain are real on this server.

If you then use multi web hosting all around the world you can multiply attacks 1000 domains * x web hosting = DDoS, every seconds or even milliseconds.

Security concern.

Example show 3rd party server which every 20 seconds check for domains which are parked on our server. This could happened when user more from one web hosting provider to another.
