I'm surprised you got this kind of feedback. I would say that you are very far from those who create low-quality posts. But JollyGood, as always, has its logic, and publication in its topics suggests some incidents. I don't know what he wants to see as quality answers, but I would just skip JollyGood's self-moderated threads.
And as for managers, I think that to evaluate a user by the quality of his posts, it is enough to set aside some time to read his posts and form your own opinion on whether to accept the user into your company or not.
