I get the idea of not allowing pointless farming kinda. But the issue is that we don't really agree on what farming means.
I'm sure extreme examples are easy, like Haejin. But, what about a dude that just loves to write a lot. Is he farming for posting two, three times? How many posts are too many posts? Is 4 posts that add up to 2 dollars too much? Says who?
That's my beef, so to speak.
It's all a matter of opinion and we don't have to all agree. The system was designed to be 'policed' by the users and some choose to use their power like this. I have done my share of downvoting, but most have never done that.
