Is Klei ok with griefing at their own servers?

So if you ever played a Klei hosted server you have encountered them, the griefers, everything from base burners to wall spawn tenacles/spiders to pick your gears, gems, mandrakes and quit and so on.
As far as I know no mechanic has been implemented to suspend that kind of behaviour.(other then comunity mods)
So feel free to express you opinion.
