Why am I not able to add a comment on the "Who is Hiring" thread?

I don't see the option to add a comment there, I was a bit late to the party as it took my org some time to draft our roles, but when I logged in to post today, I couldn't see the Add a comment option I see usually? Possible answers: The thread is time limited and I missed the deadline? Some sort of account ban due to low karma? (62) Or some inactivity log (unlikely)
