I found a solution to a "hot question" and want to share the answer, so I joined this site. But, the powers that be have deemed me unworthy of providing said answer bc I'm new. Great. So I'll write this question to earn my "reputation" points. What a joke.
Sometimes when a post goes to the "Hot Network" it gets a lot of attention. This attracts all kinds of very low quality answers that aren't much better than comments, repeating what has been said or even downright misguided answers.
To lower the burden on the curating part of the community the question can get protected (by vote or automatically) so that people need to have some minimum number of score to answer.
Its possible to reverse this protection but we would need to know what question it is you want to answer. Another way is to answer to another questions instead and get the needed score. Unfortunately you don't get any score for this post since its a meta issue (a issue of how the site works), and meta does not award score. So on meta score is more a voting structure than moderation.
