Humor requires a willing audience otherwise you're the only one laughing. Joke all you want but support forums work the best when OP questions are answered as directly as possible. If I were moderating, I'd stop this stuff so that customers are as satisfied and enthusiastic as possible.
That assumes that moderators are capable of controlling content and intent of members - which is not possible.
You cannot hold others to standards that you yourself cannot be held to. I cannot stop you from disagreeing any more than you make me agree with you.
I've seen it from both sides and placing the responsibility of 'how' to post as a moderator begs the question. You cannot control people from posting in any manner; and you surely cannot - which should be obvious - control the manner in which any post in interpreted.
I personally believe that moderators are people and if you don't 'get' someone else's humor, even when told it is humor, that doesn't change the nature of the person. There are some sarcastic people with dry wits. You cannot expect them to not post.
Keep in mind, when I use humor (which may or may not be funny) I personally use similes to indicate the intent to be funny. Whether or not you find my attempts at humor funny or not... well, I can't help it. You aren't paying me to make you laugh. And moderating on this forum (and most others) is a 100% volunteer position with no rules on what you can or cannot post.
In other words, you cannot legitimately hold the position that moderators cannot be part of the community they participate in. If you are of that mindset, then you best avoid forums that are moderated. It's not how it works.
I say that as both an active member of many forums (beyond just music and music gear forums in addition) and then also being a moderator and/or owner of multiple other forums.
You are asking for the impossible.
Moderators are people too.
And the ones that are having issue here with what I am saying are - again - taking this all far too seriously... which is the core issue. Find the humor. These are forums, not real life. Moderators are not police with riot masks on waiting to bang you on the head; they are guys just like you.
I am not working for Fractal. I am here as a volunteer moderator. I do not represent Fractal. If you have an issue with Fractal, then you are advised to take it up with them. If you don't like the way Cliff posts, then don't read his posts. If you do, I hope you read them as humor, because having met him and talked with him... he's a wicked sense of dry wit in that New England way.
