## Proposal to update `min_untrusted_score` in Kusama

> Add to proposal comments:

On [2022-12-12](https://kusama.subsquare.io/referenda/referendum/16) this [referendum proposal](https://kusama.polkassembly.io/referenda/16) was executed to, among other things, lower the `min_untrusted_score` to deal with a [mass slashing incident](https://forum.polkadot.network/t/kusama-era-4543-slashing/1410) in Kusama.

This proposal aims at updating the current `min_unstrusted_score` in Kusama back to sensible values. The new minimum untrusted score was calculated by averaging the last 30 election scores and halving them (starting from election at block [#17416892](https://kusama.subscan.io/block/17416892)).

When enacted, this proposal will change the current untrusted minimum score in Kusama from
