As topic says, checked the leaderboard and its quite many people that have fishy exp numbers, but the rank 1 player which scored lvl 50 in 35 min is the one that stands out the most. I didn't find anything on this, so.. how to report someone?

well, i guess art1f1c1al is testing ...

Stop being jealous at his awesome skills, he's so good at the game he achieved lvl 50 in barely 35 minutes
