What appears to be a SoCal poetry community in-joke.

Actual quote from a description of a link to a SoCal poetry listserve, written by the listserve's creator:

"Subscribe or unsubscribe to the Cobalt Poets e-mail list. Also sort through the message archive or join in the un-moderated fun by posting anything you want about anything at any time for any reason."

To the above quote, I can only say:
A lot of people are comfortable with/unquestioning of the "my site, my rules" policies of websites that allow comments after posts--or listserves where, in theory, a member can post on a topic of his/her choosing.
Perhaps this is an oblique way of stating this rather than writing something boring and technical
i.e. "if you post anything that isn't a reading announcement and you criticize the community (or someone in it), even if it doesn't descend into blatant insults/profanity, then I will moderate content and possibly ban you."

So now, as the late commentator Paul Harvey used to say, you know the rest of the story.

UPDATE: The proprietor of the Cobalt Poets list, via Facebook, posted an answer to this post.  And, in the interest of equal time, here it is:
Thanks for bringing this to my attention Terry. That was written when the Cobalt Poets email list was created, when, as a naive poetry host I thought having an unmoderated list was possible and before, as you know, so many people, yourself included, used it as a bully pulpit. I'll be editing the description to remove the 'anything goes' implication of the text. More good work sir!

My reply to the proprietor's statement: Always glad to advocate truth in advertising.
