Why can't you see that you shouldn't be aiming at having fewer rules. You're missing the point. Rules don't work, they don't solve the issues you're trying to use them against. And most importantly rules cannot produce better content.
As for spam consider the following: "No spam" as a written rule is retarded in every sense. It has been used to ban things that don't even resemble spam in the past. Second, if we assume that we all agree on what spam means, which is flooding, then it's assumed by anyone with a brain that the rule applies to all boards unless the board is called /intl/. Third, saying you will ban spammers does nothing, because the spammers in question don't care about being banned in your board and will spam anyways.
When a BO adds "no spam" as a written rule, you can tell he has no idea what he's doing.
