Usually if you ask to be a mod (almost anywhere) you'll never become a mod. It destroys or greatly damages your chances in an instant.
I don't see why a lot of people desire to be mods. When you're a mod you have a lot of responsibilities and the other admins need to trust you. It would become YOUR time-consuming job to make sure people don't break rules, and to only punish those who do.
This is the way how it works on every single Forum, you have to be chosen, not request it.
We also had one person on the old CW-Games Forums (DSHack.org in 2004-2008), keeping up to become a Moderator, because he wanted to be one 'freaking badly'.
All of us were just reading his posts, took some popcorn, and laugh.
However, this turned out to be annoying, so he ended up being banned.
