Your application is reviewed by people who are not self-serving and who know what they're doing. In all likelihood, if you've been rejected twenty times, you have not been rejected by the same meta editor in all twenty cases. You were probably rejected not because your intentions were viewed to be bad, but rather because your example sites were not of good quality, your titles and descriptions of those sites are not what we would want to see in the directory, something else you said or your writing style reflected poorly of you, or any combination of the above things.
I apologize if you see this as harsh, but if you've been rejected that many times, you (1) have way too much time on your hands for filling out applications, and (2) you need to find something new to occupy yourself with. That many rejections tells me that you're unlikely to get in on the twenty-first, second, or any subsequent try either.
