[Dnsmasq-discuss] Request for brain-storm: Rogue dhcp-servers on

I know this is a bit off topic, but maybe someone on the list has some
thoughts on this:
I'm running a router for a group of people connected by lan. And I
use a dhcp-server (dnsmasq) on the router to configure the clients.
But increasingly often, someone has connected another router to the
lan, usually to use it as a wifi access point. And since they don't
know what they are doing, they connect their own router's lan-port to
the big lan instead of using the wan-port. And so we get a wrong
dhcp-server competing with dnsmasq.
Every time this happens, I have to track down the rogue router by
testing each cable of the lan. Quite time consuming, and until I get
it done, the network is very unstable for the users.
Does anyone have some ideas as how to mitigate this problem?
