Those on the list may or may not be real people. I have been told a lot of the people who apply are just ‘scammers’ who want permission to put up non-Ubuntu stuff on the wiki. Because of this a lot get no further than pending.
Having looked at this list in the past, you have some karma (lp) and joined a team in 2015 (not just 7 random teams the same day you applied to join wiki-editor), a search shows you on ubuntu forums… etc… Most of the names that have been there a long time get no results for these simple tests.
For myself, when I applied; I was granted as I recall within a week. The progress goes faster if you have a reason & the team you’re involved with supplement your request.
I’m not someone who approves anyone, but am only expressing opinion that there are reasons many never progress.
