This is ridiculous.
Strictly defined rules? loopholes?
This isn't state law. Your rules have a clear intention behind them, and members should use their common sense to decide when their behavior doesn't follow that intention. You shouldn't have to get a law degree to write rules for your site.
It's not like the people who got warnings read the rules first, said "aha, so with the exact wording of this rule I can do this and that because of its loopholes". No, they did whatever they wanted, and when they were accused of violating some rule, they read it carefully and started nitpicking the wording because they didn't want to admit they were wrong.
I'll tell you a secret: most people who use this site didn't read the rules. I myself only briefly skimmed them. And yet, most people aren't violating any rules. How is that? well that's because they have common sense, which tells them what's ok and not ok to do on ANY platform.
Also, your moderators should be able to ask anyone to stop doing anything that seems wrong to them, even if it's not a part of the rules, and be able to use disciplinary actions if the perpetrators aren't listening. They are your moderators because you trust them.
At the end of the day, you're dealing with people here. There will always be violators, and others who will simply be unsatisfied with your work. But if there's anything to learn from this poll, is that you're doing just fine.
