I’m having this problem too. One user abusing the flag system. Kicked up a huge fuss when demoted to TL0. The flagging is the only problem so I already reduced flags to 2 per day.
I wonder if there’s a way we could add a user to a ‘no flag’ group and stop them from flagging completely?
I’d also welcome an algorithmic temporary ban on flagging triggered on a bad flag together with a low flag score.
