Catching all the intended comments would be hard, but it also doesn't take much... I'm "not much" in the klout department, but I hid some obvious copy-pasta yesterday with a very low percentage flag... even a "fractional" (less than 1%) flag vote from a 50,000SP account could deal with a LOT of garbage.

I think the idea here is less to "catch everyone" than to send a clear message to the hordes who are arriving here from Amazon Mechanical Turk that "clicking for cents" is NOT a viable (profitable) endeavor on Steemit.
