I thought this deserved a quick mention for craziness and maybe some points for raising the issue that seems all to often sweep under the rug - possible abuse of power that takes place at DMOZ. I apologize in advance if the below website offends anyone, but for the most part I think if you create a website called "Corrupt DMOZ editor" and intended to let people know more about the inner workings you have some courage. There are really great people that work as volunteers at DMOZ, I have met some, but as the saying goes. A few bad apples can spoil the barrel.
The website, called Corrupt DMOZ Editor was created by a DMOZ editor who under multiple screen names (and growing) takes about the inner workings in details. She is taking the approach that before you can see the light, you have to deal with the darkness. Such as How to Bribe A Dmoz Editor. basically what you do is send the editor some funds via Paypal, before doing a submission, next submit your website to the category, and viola you have a listing. She also talks about abuse in regards to editors who routinely delay submissions or inclusions for certain areas, and sometimes even erase the submissions. It goes on to say that corrupt editors work in groups even mob units in order to benefit from the directory. You sometimes have to pay a boss above you a cut of what you take in. Whether the benefit is money, one way links, control, blocking competitors from submitting and others. Pretty darn digusting if you ask me, if true.
She goes on to talk about the prime reason she started the blog here. And how hot a commodity DMOZ links have become. If there is a microeconomy and people involved there is bound to be someone who will eventually abuse it. There is another post of of interest that talks about how to Sabotaging a Competitors DMOZ Listing for Fun & Profit. I personally wouldnt try any of those methods if I were you and I would stress caution on some of the things said on the website. It seems like submitting is huge waste of time, and while I have submitted to DMOZ for many years, I have decided last year to stop totally, realizing you can spend your time more wisely getting better links elsewhere.
