Possible solution to flamebaiters/provokers
If a person gets a chat restriction or 14 day ban. That player could gamble an extra "strike" on their account. For ONE PLAYER in any of the games listed in their reform card. Claiming provocation. This would flag their account for manual review. If found guilty of instigation or egging on. That player would be escalated to 1level higher thrn the retaliator's punishment status. The retaliator would STILL BE PUNISHED. But they can have desperately needed assurance thay the person provoking them got it worse.
If it was found that they are lying, or THEY were in fact the instigator. They would be bumped up an additional tier for wasting riot's time.
