I also called for more legit moderating...I personally don't think everyone should have the ability to summon meteors on their enemies. That's just me of course.
There are a few arguments people have against being moderated in their RP though. (And let's remember these are not my opinions but what I have read about here and on SL itself)
Some people do not believe that this rule making process here on the forums is open enough and that it winds up becoming a simple handful of people who wind up creating new rules for many on SL who have no idea a new rule was made.
Some people just want a more free-form RP style free from people telling them what they're doing is wrong, no matter what the rules are. They just don't want anyone to have the opportunity to tell them "you're doing this wrong, gtfo." (although granted that can still happen without official rules based on what people find acceptable)
And then there are the other half of people who DO want regulation, set rules, and people to hold others to those values and whatnot. And they typically say 'let those who don't want to follow our rules just go RP with themselves, we're not stopping them.'
And the other half goes 'but you're limiting our RP options by changing how villages and everything works.'
Etc, etc. It goes on and on forever and ever as I've noticed. And to tell you the truth, neither of them are 'correct' in wanting their version of SL to be dominant. SL was not intended to be an RP site, there are no official SL rules to RP by and even us GM's are simply here to help start new RP's, not to regulate or uphold any rules in place.
