Er, the blog post doesn't actually provide anything other than an unsubstantiated claim. Why not name the DMOZ editor, show a copy of the e-mail, provide the offending editors' e-mail address (thereby making his life hell regardless of whether or not the ODP admins take action or not) etc etc etc.
If I were to put my cynical hat on, I would perhaps suggest this is at it's root, just an attempt to get visitors to the blog as this would be "news" in the
SEO sphere. Without evidence, sorry, but it isn't anything at all. Jaan - I'm surprised at you!
