Lately I've noticed quite a few of such "Do I need a visa ... ?" questions in which the OP does not specify any information regarding the passport he/she holds, the citizenship, etc. Here and here are examples of such questions.
Assuming that including such information is part of the "asking a good question" conduct, what should I do when this happens? Of course I could (should) add a comment asking for such information. But I feel that this type of behaviour should also somehow be "punished", very much in the style of the questions lacking a mvce in StackOverflow.
