Your own rules specify no commercial advertisements. In this thread Jord makes the post "Quick everyone, join up on the Insider Program of Skinwalker Ranch." (then provides the link).

The Insider program is a Pay Per View Commercial program the very definition of your second rule not to break. Why is this not deleted and Jord not have his privileges revoked or suspended?

Here is the link to the violating post: https://boinc.berkeley.edu/forum_thread.php?id=13563&postid=108445#108445

First off, the site I link to doesn't sell all kinds of third party books via Amazon and other places and makes this their prime intent.
Second, the site I point to is the actual Skinwalker Ranch site. They do have a shop, yes, but the main idea for the site isn't commercial intent. Their insider program may be by subscription, but then what isn't these days? (And I have the feeling that at the time I posted that link, the Insider program was free)
And third, if you feel the moderator (me) did you wrong, you can complain about it to my boss. His email address can be found via https://boinc.berkeley.edu/moderation.php
