This old question recently got closed. Just some days ago, I added a new answer to it. Perhaps my action caused the closure of the question (e.g. draw close-voters' attention).
I am interested in many old questions about inequalities in MSE. I want to give nice solutions for those problems (many of them are still open). I noticed that hundreds of those questions do not meet the current quality standards. Perhaps when this question was first posted almost 8 years ago, it passes different quality standards.
My concern is that if I continue to answer hundreds of old questions in the future, my action will cause the closure of those questions. If so, I should not answer those questions? In my opinion, they are difficult and interesting problems. Due to some reasons, many authors of the questions can not return to edit the question (e.g. give attempts) to meet today's quality standards.
