Wasn't there a bot on Voat that posted an archive of each link in the comments?
There was but this has at times been counterproductive. Raising the barrier to posting slightly would likely improve the quality of posts overall, in my opinion.
I'd draw parallels in car ownership. When someone illegally speeds in their car, you ticket the speeder instead of lowering the maximum speed of the car.
Good ol' Derram! We gotta get him to move over here to the good site!
