Show yourself on mutual buddy lists
 

Right now there's an option to hide yourself from the playerlist if you're on another server. However, it's either hide yourself, or don't hide yourself. The problem with not hiding yourself is anyone can buddy you and see what server you're on.

So I propose an option to show yourself only to players on your buddy list, if that's possible?

It should be since buddy lists are stored online. This is a great idea, actually.

It's more of a stalking list right now, perhaps an actual buddy system is in order.

I made the same request 2 years ago here. Comes equipped with replies from Stefan.
