Hello
I recently installed a squid proxy server in my server and unfortunately I left it without a password for 19 hours. My IP get blacklisted in some blacklist organization. I make a complain and they remove the blacklist. My ip is clean now.
Also I have removed the squid proxy server but whatismyipaddress.com still shows my IP as confirmed proxy server.
Is there a way to avoid my IP being displayed as proxy server?

It will show that for probably another week.
