>I wonder if there is a set procedure DMOZ would like site owners to follow if they have good reason to believe that the category has been compromised by an editor with a conflict of interest?
Actually, this is a fairly simple procedure:
Go to the top category involved. In other words, if the problem is happening in "Society: Issues: Labor: Slavery: Sudan,"* go to "Society."
Scroll down to the bottom of that page, and you'll see this:
>Category editors: dmozmarch, herbridg, inge, indianpipe, techieguy, tedres
Those are the "top Society editors."
Send email to one of them explaining the problem in detail, examples which might make investigating easier for the top editor, and your email address.
Our top editors have generally been with the project a long time, are staff or metas, or have otherwise gained positions of trust.
IF you don't hear back from them in a few weeks, go to Plan B: Email a meta or editall who will assist you.
I will not post those names here but will ask that any of them reading this post do so.
I am certainly one of them.
