Or in other words - for automatic exchange of one thing for another.

Debris from the machine (exchange debris on points) are planning to get rid of cells by tagging content as inappropriate - as soon as the cell attains sufficient votes against, the system prompts the user first approached to clean it and give him a bonus point. If everything is really bad, throw garbage owner of the machine.
