The scourge of cheating is changing speed running

[dlevere]

How do you catch fakes when it's easier than ever to manipulate video?

When an Australian gamer called “Anti” completed a full play through of Grand Theft Auto: San Andreas in a scant four hours, the feat almost seemed impossible. Yet any fans of speedrunning—an activity where die-hard players jockey to complete the game as quickly as possible, with different rulesets forming discrete “categories” of competition—could see this incredible “run” for themselves on the game’s leaderboards. Anti had posted the entire thing online.

An old saying may be coming to mind, and yes: it was too good to be true. A fellow competitor started analyzing Anti’s videos to optimize their own in-game routes, but they noticed that several vehicles in these runs left a faint smoke trail when they accelerated. Since no other runs on the GTA: San Andreas speedrun leaderboard evinced this telltale exhaust, this competitor began to wonder: was Anti somehow messing with the game in order to pull off this record-breaking time?

I've been hearing about this a lot. And people are genuinely concerned that we are getting closer and closer to a point where it'll basically be impossible to tell if people are cheating their runs.
Another issue is the people that run the leader boards for certain games, know for a fact that runs are being cheated, but are leaving them up anyway and ignoring it.
This has been happening a lot in the Zelda Link to The Past leader boards.
