Much better way to flag suspect leaderboard entries. Rather than be the Prosecution you are just a judge. Much better way. Simpler and honest.
Each ride segment is analysed and if a leaderboard entry is suspect it asks if you want to flag it, based on cadence, heart rate, max speed etc.
This is much better than trawling through leaderboards yourself because it prompts automatically, asking if you think it's legitimate or not.
