Any way to hide the amount of players in a server?

I am having a few annoying players who we believe are cheating. We have noticed when we are vanished people can still log out and check the amount of players in the server so they tell if there is an invisible Admin before doing anything bad, it pretty annoying.Is there anyway to make it so it says ?/40 or something?

thx for any help

 

How do they know its an Admin logged in instead of a player from the server listing?

But yes you can use MOTD plugins to change it or fake player plugins.

 

They can basically quit then in server list see the lets say 10/40 then go into the server and press tab and see 8 players on the player list so they know that 2 mods are hidden.

Ty for the advise tho ill look that up

i found MOTDmanager but it doesn't give me the option to hide how many are logged it just the max possible on the server. is there a a MOTD mod that i should be using?
