I wonder what we can do about fake users, callsigns, locations?

In the last 24 hours A1XYZ has appeared in Antarctica, as did QP1WCE. I am pretty certain that both of these stations are in Belgium / Germany / Netherlands. I have had this before, it is really frustrating.

I don't know what to suggest. Any ideas or suggestions?

Cheers,

Jon.
