A few days ago I flagged a question to be closed/removed since it is old, the user is not around, the question hasn't seen any activity in years and the problem didn't got a solution, or at least, the OP never mentioned anything, the question is Subdomain still times out after being set up a month ago. Also the situation seems not just too specific, it seems so unusual that doesn't look right. I think that there was a misunderstanding or misconception on the question, but that is just my opinion and is not too relevant for the situation.
Well, it got a good answer from Stephen Ostermiller, from a good knowledge about how assigning IPs work. Which the user didn't seem to have.
So, I got a very reasonable answer about that, it's unfortunate, but having a question that was abandoned is not uncommon. My opinion is that, yes it's unfortunate and yes it's not uncommon, but that is not a good reason to keep the question around, isn't?
And just by coincidence, I stumbled upon this message Cleanup: unanswered questions from 2011. I don't think a new answer should be written since there is no point, the same applies to upvoting, the same to editing the question, so, the only option is to flag it, which I did.
So, no just for this question, but as a general rule, should questions like that one, which are not just old, but obviously not going to get any good answer and even if they do, there is no way to know if that answer helped, be flagged to be closed or not?
By the way, I saw some old answers to related questions, but I didn't feel that those addressed the situation. Although some are good guidelines.
