Be aware that any kind of "RTFM" suggestion, including "google it yourself", is likely to come across as snarky, if not downright nasty, so be really sure that's what you intend for the OP before you do it.
I don't think that having one "RTFM" type answer among the several that a querent receives is necessarily a bad thing. In some sense, it's all part of the XY problem domain: an OP getting a spectrum of responses may be better than getting only a number of nearly identical responses.
I think it's usually better to reply with a link to something like How do I post a question effectively?, which has rather comprehensive advice, including the admonition to do an appropriate amount of research before posting a question.
I reckon we are the only monastery ever to have a dungeon stuffed with 16,000 zombies.
