Is a rejected Mturk application for life?

Forgive me if this has been covered elsewhere already, but I get so down when people post their “how I made $X” and Mturk is listed as their biggest earner. I applied earlier this year and was promptly rejected for reasons I can’t even begin to hypothesize. I am wondering if anyone knows how this works; am I out for life? Is there a workaround? Any clues about most common barriers to approval?

Any tips or insight is appreciated!
