Time Trial - Nurburgring 24H Cheaters and Random Leaderboards Wiped

Hello all, someone figured that they can skip the entire first sector on the Nurb 24H layouts and a bunch of copy cats have ensued ruining the TT leaderboards. Would suggest keeping the Nurb GP sectors as silent checkpoints to prevent cheating as well as wiping the times of said cheaters. They can be easily identified with absurdly low first sector times. I would really hope the entire leaderboard doesn't have to be wiped.

I have also noticed that random track/car combos have had their leaderboard times completely wiped. A few weekends ago I especially noticed this with tracks starting with the letter V such as Velo Citta and VIR. F-Inter and Stock Car 2022-24 are good examples of having their times wiped. Is there a reason why this would happen?
