Any form of "committee" flagging of posts or comments in order to reduce the payouts would need to be timed properly
For sure, everything that matters shall be taken onboard and the right way of acting shall be defined. Flagging could be more or less an automated process, initiated by some human effort based on the outcome of the investigation. Maybe we need 2 different flags in our community: 1) reduction of Reputation 2) reduction of post/comment rewards. As a 3rd measurement: blocking of an account could be introduced.
someone for a public wall of shame would make that stop almost immediately
I had this in mind as well, and commented to other post that such social control will for sure help. The analogy I drew was with our strong religious communities in the Netherlands were (almost) all individuals living in such towns and villages go the church and those who do wrong are called out in church so everyone else knows who and what. The result of this is: Everybody can leave their doors to their house and cars unlocked and nothing gets stolen.
