I wasn't calling out Affinity's fakeclaim. That was the first example other than absurd lurking that came to mind at the time. Affinity may have did it badly, but it definitely wasn't his intention which I think we can all agree on.
I agree with you that policy lynching doesn't further my wincon. As much as I want to do it when I play, I end up not doing it because it is simply not the optimal play for my faction, town or scum. If not to policy lynch people into dropping a play, then it's again a community thing where everyone must agree to an etiquette of not doing that play.
The card system is for systematic handling of modkills. Getting modkilled in a game means you did something unacceptable by the rules that were laid out. The idea was drawn from professional sports where players can't abuse commiting fouls in a game without any consequence. Repeatedly getting modkilled for inactivity would get the player red-carded as the system expects to do. But what we have is someone skirting the rules. In that case, reporting the player (in the MMO sense of the action) or making it public that what they're doing is game-ruining for others, also sends the message to them to stop that. The extreme solution is to bar the person from playing entirely, though we're far too nice to seriously do that.
