Whether it is illegal or not mainly depends on whether the content you sell is fraudulent or steals other people's online information. Or whether it infringes on the interests of the game company. Those who cheat or something will generally be prosecuted. Otherwise, some small cheats such as one-click combos do not affect the fairness of most ordinary players, and the game company will not care. Many cheats that are reported are generally not discovered by the game company, but are usually done by your competitors, so you should also pay attention to your competitors.
