Leaderboard goes up to 238,105. Personally if you're that far through the game on the Fake Lay site, I probably wouldn't abandon that progress. The only other upside with Nutaku though is that if you sign up for their e-mails, they will send you every few days a code that gives you 100 points. (Worth $1.) You can save points up to eventually buy diamonds or other things in the shop.
