This referendum cleans up all undecodable keys from storage.
The first 19 keys removed are undecodable Locks, which were not migrated correctly during a runtime upgrade in 2019. See <a href="https://github.com/polkadot-fellows/runtimes/issues/104">this issue</a> and <a href="https://github.com/polkadot-fellows/runtimes/pull/122">this PR</a> for more info.
The remaining 381 keys removed are undecodable, inactive SessionKeys also likely created due to a bad runtime upgrade. See <a href="https://github.com/polkadot-fellows/runtimes/issues/140#issuecomment-1898081577">this comment</a>, <a href="https://github.com/paritytech/polkadot-sdk/issues/1149">this issue</a>, and <a href="https://github.com/polkadot-fellows/runtimes/issues/151">this other issue</a> for more info.
This call was programatically created and verified for safety checking that
<ol>
<li>There are no longer any undecodable keys on Kusama</li>
<li>Only Locks from the faulty 2019 runtime upgrade are removed</li>
<li>No session keys removed are from the active validator set</li>
