We currently have three off-topic reasons:
- Requests for illegal materials
- Reading recommendations
- Unannounced future events
I feel that all three are reasonably used today, and I've noticed another trend which isn't completely new, but I start noticing it more and more.
I propose a fourth off-topic close reason,
- This identification request contains too little detail to be answered. Please refer to these guidelines and add more details to your question.
I know this falls under the subset of "Unclear", but I think a close reason specifically for that, with the appropriate links and explanations is a good idea. It's not always clear to users what we expect of them in these types of questions.
