For those having problems with applications, I think I remember having problems in the past due to .ml TLD often being blocked my mail servers, due to being used by SPAMmers and other evil-doers. Maybe those awaiting for a reply should look into the SPAM folder if they have one.
Also, essays aren't needed. You just have to show you aren't a bot or troll and actually want to be on the instance. 3 (three) or 4 (four) sentences in my experience should be enough.
