Have you ever played a game that links to Apple’s Game Center and wondered how on earth anyone could legally achieve such high scores.
Well Apple has the answer. It advised developers of the following-
“You can now view and manage the top 100 scores and usernames for all of your Game Center leaderboards. Protect your legitimate players by signing in to iTunes Connect to delete fake scores or block players that post fake scores. You can also restore scores and players within the same time period. To learn more, read the Managing Game Center Leaderboard Activity section in the iTunes Connect Developer Guide.”
Long overdue feature in my mind.
