Indeed, a reform would be nice, but what can we -actually- do? Experienced as we may be in roleplaying, that doesn't make us superior to any other member of the community regardless of their skill in the matter at hand. As Hype said, we don't have any power over anything to change it. Even if we openly declared that "So and so is now the new RP standard, everyone who doesn't agree, door is that way", people can just say "Nope" because we can't actually prevent them from continuing on with their threads the way they were before.
A lot of us know how bad moderation feels in RP communities, as we've been on the receiving end, but the irony is that this forum owes existence to people who couldn't moderate themselves, so Riot had to do it. The Ask trend was very interesting to them at first, but after it flooded out the first page of the Lore forums with mediocre-quality threads, they split them off in a very diplomatic manner - I'm still thankful that they didn't delete everything, which they could. That much should at least hint something.
As sad and pitiful as it sounds, we're approaching a certain critical mass, a point of no return, where some sort of forum moderator powers will be required to maintain RP of a decent standard, because clearly, the players aren't able to do it themselves despite the repeated attempts at it. We're a very democratic community with equal rights, but while it has a lot of advantages, it also prevents us from telling anyone what they should do, and allows people who didn't prove themselves to be worthy of taking up a Champion role (which, in official RPs, was entirely restricted from players), to take a thread or several. No one can change those people if they don't want to change themselves.
