Sort:  

I'M really not sure I understood their crowdsource concept correctly but if so, flags would have a separate pool and would be non-linear.

I came up with the idea of independent flagging pool, Here's something I posted about it.

There is only one user involved when down-voting so there is no "crowd" per se.
