Anyone with experience on most Reddit subs knows that the real problem there is mods abusing their positions, not admins.
You can talk about free speech all you want but if moderators are local dictators just like on Reddit then it's not going to be much better for most people. And if people squat on namespaces they took early on, there won't be good places for many people to congregate.
The Donald just got quarantined on Reddit. So people are coming here, but who moderates it here? /u/magpie, who has not posted in 9 months. Does this sound like a place that lots of Reddit users are going to jump to?
Reddit has a reddit request system, and implementing something similar should be done here before it becomes a noted problem.
