Just joined. Spent almost a whole day of my life critiquing a story that promised 2 points. Clicked submit and what do you know, I got 0.5 points. This is a ripoff of your time. Don't use.
Note: this wouldn't have been such a big surprise if the rules were clear. But the FAQ doesn't say: dear user, you do this on your own risk and you might not get any payoff out of it because that's just how we roll. No, you're left to find out at your own expense. And there's the option to go bed a moderator, maybe you get your points? So you need to work more and spend more time, and ask nicely for what you were promised in the first place. Bait and switch, it's what this is called, and in a world where businesses are regulated it would be illegal.
