Hanging on my bathroom wall...
"Don't take anything personally.
Nothing others do is because of you. What others say and do is a projection of their own reality, their own dream. When you are immune to the opinions of others, you won't be the victim of needless suffering."
It's stolen from a book by one of those mystical self-help guru types. I only mention that because most of the rest of his book is garbage... in my opinion. But his little list of commitments to make to yourself is dead on. That is one of them.
It has some moral problems if you're a leader or instructor of others. Beyond that, generally it's a good platitude to remind oneself that one's life is one's own, and you DO have a choice as to whether or not you ALLOW others to ruin it.
You can be a victim or you can choose not to be. People will always have their opinions. Bottom line.
As far as running message boards goes... It's a thankless job. BTDT.
IMHO, it's not the MC's job to make sure no one is offended. The MC sets rules and has volunteers to enforce them. Anything beyond that is a problem in the recipient's head. No MC will ever have a comprehensive list of rules for every possible scenario.
That list of rules thing someone posted above is how we've handled the perceived problems on other boards I have been involved with. Message breaks rule #6. Deleted. Published rules, no surprises. People make mistakes.
Going to go watch the thunderstorm now. Cool stuff. Managing humans/babysitting, boring.
