Here be cheaters

This is so not cool.
Just found out the hard way that it’s possible to cheat on Game Center.
We want to clarify that the problem is NOT on our side, it’s a problem for every game that has leaderboards on Game Center. There are a lot of other developers experiencing the same thing.

How is this possible? People with jailbroken devices can access files they normally would not be able to access, and manually send whatever score they want to the leaderboards.

So, it’s pretty sad for us that like to compare our scores. Good thing we implemented Facebook scoring.

So, what can we do about this? Basically, nothing.
Then who should do something about this situation?
