Noticed this methodology too several times.
What you really can do at the moment, ist reporting the server.
Here you can find the official server hosting rules and contacts:

Sadly the hosters are not consequent enough in my opinion. They don't really shut down servers. The Admins know that and don't really change their behavior...

I guess at this point bohemia is in charge...

Hi Gasmaskjohn,

As Nihil Baxter mentions, you can always direct servers like this directly to the GSPs: http://forums.dayzgame.com/index.php?/topic/158966-dayz-standalone-server-hosting-rules-server-reporting/
