On Consoles they have controllers with remapable paddles. These type of controllers are not considered cheating and are allowed in competitive gameplay. One can simply map two paddles to the same button (interact) and break from the net almost instantly.
On PC we have two commands named Jump/Interact and another for Interact. One can simply map two adjacent keys to these two commands and alternate super fast between them, getting you out of the net almost instantly.
Is this cheating? No. No one is altering any kind of game files or using third party software to hack the game, which is what officially is considered cheating. Is this an exploit? Maybe, depends on opinion more than anything.
One simple solution is for the developers to eliminate the āmini-gameā and simply put a timer to get out of the net.
