This post isn't necessarily directly related to fighting games. Though, in a way it is related to all games due to web chat forums and other services that our online communities use.
Basically, I find it ridiculous when people complain about moderators or rules for basically any medium.
Say you owned a site, and other people enjoyed that site a lot so they asked to join you. Now some of them are doing something you don't like on YOUR site, do you let them continue? Of course not, you are the one paying for a site that you're letting others use for free. It's yours to do whatever you want with. You don't owe anybody anything and so you kick them the fuck off if you feel like it.
So anywhere from places like PayPal or Amazon to smaller places like Shoryuken.com/forums and Dustloop.com/forums, or even places in between like Battle.net or X-Box Live
They don't owe you anything. It's not yours. They are allowing you to use their service under specific rules/conditions. They offered it. You are not entitled to jack shit. It's not even a "public" service either since they are all independently/privately owned. They are simply inviting "the public" to use their service under a Terms of Service agreement, which they can make up or change in any way they please, any time they please. They do not need any reason what-so-ever to moderate or ban anybody, regardless of whether it makes sense or not. They're allowed to, because it's their site to do whatever they want with. And they can put people in charge of moderating as they see fit.
Let me clue you in on a little bit about copyright. You are entitled to copy right when you create something, but only when it's an actual public place. When something you create is entirely yours, including the space presented, then it's actually yours. But when you get right down to the nitty-gritty a WIKI is not a public place, it is a privately owned service/server. What you contribute there is your responsibility, not the wiki owner, and it is no longer yours when you contribute it. If the owner were to shut down or use it for their own prosperity it would be within their right, entirely.
Of course, if that sort of thing isn't logical and/or if it happens often in a negative way (or happens to "you" since lord knows you're special!) then yes it's a shitty service, then just get over it and find another service that isn't shitty or fucking deal with it.
See, personally I remember a time back before web forums, deviantart, photobucket, XBL, BNet, and all those other places didn't even exist, which is really only a couple decades ago for the majority of internet services. Thus, I am so sick of hearing people complain about moderation/ToS. It's even to the point where I'm also sick of hearing the moderators complaining about the spoiled ingrates that complain to them.
