Believe what you want, but it dosent make it true. The fact is you broke the guidelines by submitting numerous times, if that is what you did. If you recieved an email about this, well I would assume that you did it more than just once or twice Emailing editors also isnt the wisest course of action. It certainly sounds like spamming to me. No site is guaranteed inclusion in DMOZ. It sounds like you wanted a guranteed listing, in which case you should be looking at many numerous other directories that provide such a service. DMOZ only accepts suggestions and they may be reviewed, but no time frame is given.
You tried to get your site listed in a directory by regular submitting and emailing the editor for three years, despitre their guidelines, and now you call the direcory a joke. Now what sort of person spends time doing that?
