So far, my experience has been to just ask nice and be persistent. Have clear and concise reasoning and the ability to prove or backup the request with sincerity and you should expect to see the light to approach that trusted list. Mistakes happen! Enthusiam in inputting data in my own family tree, which was personal for me, was just as personal for others who thought me careless rather than exbuberant. It was overcome and I was "allowed" back onto Wikitree, which I was stopped from using and had tremendous withdrawal issues.
