Posting -1 and some other stuff with no literal reason why is not going to help anyone.
As for the topic, I would agree with the suggestion. It's a pain in the butt when someone is able to play at such spikes, I myself am lagging like that nowadays and it's frustrating for me, I also know it's more frustrating to players who are victim of facing such a lag.
LW has the temporary ban upon 5 jitter/ping warns for an hour, that serves greatly. As said above, 2022 is on us and still such a delicate connection is simply not fair.
A step is needed in this case more than ever now, and the tempban per 10 or less kicks seems fine.
