Stumbled upon this post

It's funny, I though it was only me who's had this problem.
FlashCash switched to NATS some time ago, and ever since my signup ratios doubled (got 2x worse). All flashcash webmasters are reporting same problem on their forum, but FlashCash is saying that everything is fine.
I know for a fact that something is wrong. Your ratio can't just double for no reason. I've had the same, very steady SE traffic for years and all of the sudden ratios go to shit overnight? Smell like bullshit.
So what the hell IS wrong with NATS?
