Unlikely mappings TTN Mapper

Since a while we see unlikely mappings from more then 1000Km with RSSI rates we all dream of.
Would it be an option to build a restriction in TTN Mapper that blocks mappings with distances that are > e.g. 400Km, or can we mark these mappings as experimental and remove these from the main map?

It would be sad if the mapper is no longer representative to show real mappings to interested audience, and we all build individual mappers.
