The distinction is important as it decides how the developers and community responds to the issue and to the players who exploit the issue. On the one hand exploits can be considered illegitimate cheats that the developers should address and exploiters should be banned, while on the other hand exploits can be considered simply part of the game.
Arguments in favor of the cheating view involve the spirit of the game and the potentially damaging effects of the exploit on the game's community.[3][4] While the rules or game code may not explicitly disallow a specific exploit, it may be seen that using that exploit goes against the spirit of the game.[3] The potential damage of an exploit on a game has been described by an online community manager as "devastating".[4]
In defense of these behaviors are arguments that the rules of the game allow it and that players might not know they are behaving against the designer's intention.[5][6] So-called exploits, in this view, are not cheats because they do not change the game in any way and therefore could be accessible to all players if they know how to do it.[2] The players who use such techniques may consider them fair for use in the game in cases when they are not explicitly disallowed in the Terms of Service or other such rules governing participation.[5]
