As far as I remember, asking questions whose answers are unlikely to help anyone but the person asking the question is discouraged, and mind you, I learned that the hard way when I got kicked out ouf stackoverflow a few years back. Yet here on Arqade, I see lots of questions such as "[Minecraft] How do I do [this specific thing] with commands/command blocks?".
Good examples are This and This.
Are these questions allowed or should they be flagged? I mean, this seems more appropriate in a forum rather than a Q&A site, as allowing this type of questions can potentially result in one question for every possible thing you can program using Minecraft's commands, not to mention the trouble with marking for duplicates and trying to find questions/answers on your own before posting them. So, should these questions be flagged, and if yes then as what?
