Recently, there has been some users who post a significant amount of things in the comments to questions of low-quality questions. To me what they put in the comments is really a full solution of the question.
This is frustrating for those that were asking the OP for more context of the question or were giving nudges to a solution by themselves without giving out the complete solution. It's also an issue because this seems like it's a loophole in closing questions.
I saw a case today where a full solution was posted in the comments after the question was already closed as off-topic. There was another case where a detailed solution spanning two comments to a low-quality question was closed as off-topic afterwards.
Should there be some ways to enforce the comments of off-topic questions? I am not entirely sure what the purpose of these users are; it's clearly not for reputations as they're not posting answers. Otherwise there's no point in closing questions because people will just type their solution in the comments after it being closed.
