After a recent influx of questions "here is the jpg to my homework", I thought I should get the ball rolling and post one suggested list based on https://mathoverflow.net/help/on-topic and https://mathoverflow.net/help/how-to-ask

>- **Did you read [What topics can I ask about here?][1] and [How to write a good MathOverflow question?][2]?** 
>- Mathoverflow is intended for questions on **current science research areas in mathematics**. Have you visited [Math.stackexchange.com][3] or [other math Q&A sites][5]?.
>- Mathoverflow is **NOT** for questions about **homework from high school or university.** 
>- Mathoverflow is **NOT** for questions about **standard textbook material** from undergraduate/graduate courses whose answer is already known. 
>- Mathoverflow is **NOT** for **proofreading/announcing/advertising** your (or other people's) work. Questions of the form "Is my work on this famous conjecture correct?" will get closed. 



I noticed that questions on Homeworks and big-conjectures are the two main culprits of closed questions.


Any help on modifying the language of the above points or adding more is much appreciated. Or if you have some other list in mind, please consider posting it as an answer, I would love to see it. Then by voting we can decide a good enough list.
