I found Am I conveying disrespect if I omit my gender pronoun from a conference nametag? through the Hot Questions list. I was interested in posting an answer, but I don't see the answer box. I have 101 reputation here, but there isn't supposed to be a reputation minimum for posting answers. I also see answers from people with 41 and 17. Are there extra restrictions because it's a hot question or because there are already lots of answers (13)?
Someone else with reputation = 101 posted this comment, implying that they're having the same problem: "I don't seem to have the permissions, so I'll comment my answer."
Is it because most of my reputation is just the association bonus? That doesn't count towards answering protected questions, but the question in question is not protected, at least not when I view it:
