I want to offer subdomains for my services similar to what blogspot or WordPress does with their blogging platform. For eg. subdomain.mydomain.com.
However I am getting users who are registering and abusing my service for phishing attacks. Browsers vendors like Google chrome and Firefox are marking the whole domain as "deceptive". This is harming all my customer and not just the offending subdomain.
I am using cPanel + WHMCS to offer this service with the hosting package.
How can I stop Google to mark the whole *.mydomain.com as deceptive.
