DMs can't really exploit the rules, because of Rule 0. However, DMs can abuse their authority, which is a semantical difference I will grant you. DMs who do abuse their authority should see the players leave his game behind and find some other DM to play with, or perhaps on of the players can become DM.Do you think it is a bit of a double standard that you seem very concerned by players exploiting the rules and not by DMs doing so?
After all, Rule 0 pretty much gives DMs unlimited scope to modify anything.
