I have seen a lot of very similar questions here, so I apologize if this is a duplicate. There is a related question at Closing questions that show no effort - official policy? I see this very often in MSE:
1) Someone posts a question, probably phrased in the imperative, without any accompanying context, explanation, or attempts at solution. I think this is often called a "Problem Solving Question". The question is labelled (homework) or is almost certainly homework. The question may also be poorly or ambiguously worded, containing serious mistakes, perhaps with an inappropriate title.
2) Someone leaves a friendly comment suggesting that they explain what they've tried, avoid the imperative, clink on a link with instructions on how to post questions (I've never actually checked what is posted there. I don't know if the OP's ever do), etc. etc. Perhaps they or someone else gives a good hint on how to solve the problem. If the question contains a mistake, a commenter interprets what the OP probably means without suggesting that the OP correct the question.
3) Someone else (often several people) comes along and gives an answer with a complete solution to the OP's question, without waiting for the OP to improve his/her question. I can only guess such people really want the points.
4) The OP accepts a correct, complete answer (out of at least one, all of which all correct). Someone has done his/her homework for them!
Since this happens so often, the OP may be getting his/her homework questions answered (with complete solutions) without ever posting a good question. If the OP's question(s) are put on hold and not answered, it will force him/her to improve their question. So I'm thinking of anonymously downvoting all such questions whenever I see them. I have 2,403 MSE points, and I'm not sure if I can put a question on hold. The reason I want to downvote anonymously is that I don't think I should have to justify downvoting such obviously bad questions, and I don't want the stress of disputing with the OP and well-meaning but misguided fellow MSE participants.
Here are my actual questions: is such downvoting considered bad etiquette or contrary to any rules/guidelines? Would casting the downvotes cost me any points? I'm not obsessed with points, but I don't think this should cost me any. Can an MSE member with 2,403 points vote to put a question on hold?
I am not asking what official policy MSE ought to have (that issue was discussed in the question I linked to above), just what I can do.
