Thanks, that’s good to know. 
I’ve just noticed your signature btw, and to be honest, that’s the way I love to learn, thanks for sharing that link!!!
“Plus, getting help is also tied to how much you also help others (or your own footprint on here).”
That sounds like a detrimental philosophy for anyone to adopt. I can understand people being reluctant to engage with people who appear to want a one sided relationship, but unless people can get help, they won’t gain the knowledge to pass on to others, and will be too busy trying to solve the problems they do have to spend time on a forum passing on any knowledge they do have. A Catch22. It’s a relationship likely to end in Engine divorce.
. Me and Unreal Engine went through a divorce last year, but we decided to stay casual friends. Her parents were too aloof to want to talk to any of her her friends, and her friends didn’t seem to want to give me the time of day. 
Seriously though, in addition to that, it looks bad to find two year old unanswered questions posted by someone having the same issue as yourself. If it remains unanswered because that poster is being punished for a one sided relationship, then it’s a punishment that extends out to anyone else with the same issue who haven’t done anything wrong.
I would say you could categorize reasons for unanswered questions broadly into three.
1.Unwillingness to help.
2.Unavailability to help.
3.Inability to help.
Each of these will have an impact on the other which is why I understand the absence of Epic devs will have an impact.
Also, I understand that people can get fed up with poorly worded questions but to modify a famous quote…
“For if you suffer your beginners to be ill-educated, and their posts to be poorly worded from their infancy, and then punish them for those badly worded posts to which their first education disposed them, what else is to be concluded from this, but that you first make beginners who create poorly worded posts and then punish them.”
I don’t know what would be wrong with just putting a sticky in each topic with a questions template?
