Sounds about right... there is a picture and... that's it. Show me where I can sign up for the ad network, or read the API documentation.
"Extensive scoring validation" LOL
AKA "manually removing players who don't look like slackers"
Here is an exercise for you - guess which of these entries are valid and which will be "extensively validated" out of the leaderboard:

Why does Gravity need to be rebuilt? You shilled last year that the months of delays were supposed to make it secure and otherwise great, then you shilled that it's just a foundation and the game needs to be completed. Looks like you lied. It is shit and is being rebuilt in hopes to be slightly less shit, which will work out about as well as a bandaid on a broken leg.
The only reason Gravity has any players (or cheaters as the case may be) at all is the tournament. Based on the team's track record it is safe to assume that the "rebuild" would have about the same level of success.
