We never gave permission for this invasion of privacy my less requested it.
There is no delete option even after having claimed the server and gametracker does not have permission to disseminate information gathered from within our server.

It'd be like saying because the letterbox is not welded shut it gives anyone the right to go through our mail and post it's content on your for-profit website.

So please stop displaying information related to 103.62.50.4:9999.

You may at any time follow the instructions to take ownership of your server on gametracker and then delete it (I see you have taken ownership already);

You may at any time follow the instructions to block the scanner IPs via your firewall thus making your server 'invisible' to gametracker;

No one is invading your privacy.
[correction]Your server is publicly transmitting this information
Your server is making this information publicly available to the internet generally on commonly recognised ports.
Further, gametracker does not automatically add anyone's server.
It was likely added by one of your users

Protecting and securing your server is your responsibility.

I hope the above helps you.

I'm sorry to hear you no longer want your server tracked after you added it. It's definitely possible to stop the tracking, and it is very easy for you to do so.

At some point you enabled query permissions so that your server can be added to trackers like GameTracker. Since you've had a sudden change of heart, I suggest you remove those permissions:

Otherwise, blocking the IPs will do the trick too (but it won't prevent you from showing up on the many other trackers).
