While it's true what you're saying, let's not forget that everyone started off as a beginner. It's up to him to decide whether he's going to improve by himself or continue to ask for the smallest things ever, but I'll help him to give him a little bit of understanding.
You need to take a look in ../conf/mapflag/
From there it should be pretty easy to understand if you just give it some time. It's possible to add map flags within your script, however you can also make a new .txt file, in it you need to define what map should have what restrictions.
Although, I recommend you sort it up the way you prefer it so it doesn't look messy for you
