Yeah well when I say "heard" I mean "read". I read about it, numerous times. There are reports of it everywhere, but I'm guessing you know that.
Have you not noticed that no one ever produces any evidence to back up that?What about the credibility of those who make up allegations and claims and never produce anything to back that up. What about the credibility of those who just repeat the claims in public forums without actually checking they are true. Have you not noticed that no one ever produces any evidence to back up their claims? What does that say about credibility?
Can you show us the evidence to back up your claim or are you just making it up too?
I can show dozens of [threads, [URL="http://www.seomoz.org/blog/dirty-tricks-at-the-dmoz"]blog posts](http://www.webproworld.com/webmaster-forum/threads/53028-DMOZ-editor-wants-300-to-list-my-site) all talking about various forms of abuse by Dmoz editors. And they contain evidence in the form of opinions, emails, contact with Dmoz about serious breaches of their policies.
So there's plenty of discussion about it, enough for me to form my opinion of Dmoz and question their credibility.
What evidence do you require to question the credibility of Dmoz? Or are you satisfied that everyone is just "making it up", like you suggest I'm doing?
