yeah but what do they get out of it
imagine they're bragging like "hey guys i got 15 seconds in a lego parkour game"
"nobody cares friend"
Huh? That makes it sound like winning a challenge is insignificant regardless if it was cheated or not. But with the fact that OP is frustrated with this guy cheating, and that some people were dedicated enough to grab some evidence, that's clearly not the case.
Believe it or not, a lot of people consider their virtual competitions significant because it's in our nature to be competitive-- and if it seems like there's someone who has a clear advantage no one else has, then those who care are obligated to bring them down via other means (authorities in this case).
Of course, the incentive of increasing reputation among peers (regardless if you know them or not), and having an efficient process to do so (that is exclusive to you and breaks rules, ie cheating) and getting away with it is something that affects everyone. It's another thing that's in our nature (having disproportionate power over others), and it's also why unbalanced servers/gamemodes are so popular and hated at the same time. Because a handful of people figured out a method that isn't quite obvious to everyone else and it gives them a massive advantage, and likewise there's those who hate it since they've figured out the entire game revolves around that method anyways; so they choose not to play it since it's boring.
