I'm certain most players won't want to turn up to coil with a -20% damage dealt or a +20% damage recieved debuff on them.

Hopefully somebody in their static/FC leader would then have a quiet word to them about their behaviour if they know it will have an adverse effect on their performance.

also means any pug that they get into will say no thanks and remove them immediately.
While it could very well work, I prefer reducing reward over ability. Reducing ability might have the side effect of rage quitting for extended periods and perhaps even an exodus of griefers to other games (while a good thing for victims, a bad thing for SE).

Though to add to yours, along with debuffs, they get a symbol next to their name for all to see. (still to severe though I think....)
