I think there is a 'spirit' to a game.

Take diving in football. I think it was only recently made illegal, but for a long time before that it was considered bad to do. Many bug exploits described here generally fall into this sort of category. Not strictly illegal or impossible via the game mechanics, but 'unsportsmanlike': disrespectful not just to the game but to fellow players.

To change my analogy slightly, we've got a system whereby the referees of the game are the fellow players. A system could work thus: If there's potential bug-exploiting, the player on the receiving end should say in the file, the players can vote democratically, and decide what happens. Clear the accused; give them a yellow card; or red card the offender and set them to AI or get a sub. If the offence is deemed sufficiently unbalancing, a turn rollback could occur.

If you want to use one of these strategies even when it is not stated beforehand they are unfair, you take your continued presence in the game into your own hands.
