I'm not sure if I can see anyone ever doing it because... dear god... the applications that you're up against when you're applying for any WN mid+ tier UC is terrifying. I sometimes lurk on the app chats, and I see what these people are whipping up... I don't know about spending hours on something that won't get you a definite result.
I can earn enough money in a few hours to buy that same UC, ahahaha.
