I think there should be size limits on flags. You can have national flags but these shouldn’t take up too much space.

I regret thinking about this a bit too late, but what if we* ganged up against the largest country flag in the canvas, whichever it is? We wouldn't even need to agree on what we should cover it with, as long as everyone places pixels over the same flag.

*"we" = anyone who doesn't want those big country flags.
