Addon/tool for checking a private server's population?

[SuperCPU]

Hello again,
I was playing a few Classic WoW servers lately and on some of them you can check how many people are online (using /who) - Kronos, Nostalrius, Valkyrie, on others you can't see how many players are online - /who will show only 50 and say nothing else - Feenix, VanillaGaming.

I was wandering if there is any addon or tool that can count how many people are online on a private server.

Thanks

You can count how many player entities that have been pushed to your client, you can count /who statistics, you can count based on number of active battlegrounds, etc...

But none of them are going to give you a real statistic because they are easily faked by the server.
