I see little wrong with swear words, in and of themselves. It's the context of their use that can deem them profane or appropriate. I rarely use them while talking, and even less when writing. To me they're generally used by people that have feeble minds and say them because of a limited vocabulary. Especially those people that use them in every sentence. They just don't get it. The words completely lose any possible impact they might have and just become filler.
The best cussing and swearing that I've seen is the kind where not one swear word is used. It's become a lost art, but when you come up against someone that knows this kind of talking you can be amazed at the words that spew forth with nary a bad word amongst them.
I side with grenv on this. No filters, besides ain't that what the moderators are for?

As for moderators being too arbitrary and capricious, we do need a mechanism for helping their removal and replacement. If more than a few complain about a moderator as some of you have been doing on this board about the Music board, it certainly must take some looking into. You know that's right Fencer, or you wouldn't have installed me as moderator of the Gothic Chess board. You have the power to do it, but not the time or resources to police each board and still run this site.
Perhaps some sort of polling device, or a complaints registry. We all know if you do a good job, no one will say anything. But screw up just once, and they're on you like flies on fecal matter. This is certainly the case for baseball umpires! :) If they do a good job, you don't remember them. One bad call, and that's the main topic of discussion after the game most of the time.

The other thing is sharing the job, or letting others do it after you've served for awhile as moderator. As has been proven through the course of history, power is rarely ceded or given up freely. No matter how bad a leader is, it usually takes a very bad one before the masses will rise up to do something about it. Even something as inconsequential as being a moderator in an obscure message board of a game site seems to bring out the worst in a good percentage of people. They get a little power, and it goes right to their heads.

Suppose I want to moderate a board, and the current occupant doesn't want to step down or share it. What can I do? Are we in for life, or do newcomers have any rights? How do others complain when they think a moderator is overstepping their authority? They obviously need a public forum. Looks like posting to a different board trying to drum up support is their best option. That's why people have been posting here Fencer. Same thing as to the Gothic Chess board. CothicInventor's one major mistake, and obviously the people in the Music board haven't made it yet, was to make Fencer mad. Oops!

You created the other boards Fencer. Why, I don't know, but they're here. They have nothing to do with games, but people use them. Now the monster is getting a life of its own and will take over your site if you're not ever vigilant. Short of just deleting the non-game related boards, you're going to have to come up with a solution to this soon. Poll a few of the people that care about it, including the ones that people complain about and see if they have any ideas for you. I'd make it easy for a current modrator to advice people of a board that he wanted to step down. Such as a check box at the top of the page. As for someone the wants the job, or wants a new moderator but not themselves inhis place, you need to have a way to change them or atleast let the challenger compete for the job. Perhaps he shouldn't take over as the present person is doing a good job for the rest of the people of the board. I'm not going to suggest an election or something of the sort, but you can think of something. If any of the boards are really that important to someone, let him pay for the position. A challenger could outbid him for the job. Negative comments could also be factored in. Hey, a free market for moderators! :) Such a system could work for the people that get mad at a moderator. They could pool their money by all chipping in a few bucks each and buy it out from under him since it would cost too much for himself to maintain. Most of the boards will remain as they are. Forums for like minded people.
