@sirpercival About your meta-posting problem - It turns out I was viewing your main profile (StackOverflow). You might be able to find a challenge such as
code-golf that has very few or no answers, as people may upvote your question.
popularity-contest is another one (this is designed to specifically win by most upvoted answer.) Just find one without any answers (or answers you could make a good improvement on) and you should be able to get enough rep.
