I know how to report an answer that violates community guidelines, but how does one report a question?

Hover over any part of the answer or question and a small purple flag appears to the upper right of the answer or question.

Click it, and if it's a serious violation, click the: "I think this answer violates the Terms of Service" 'button'. Otherwise choose the other one.

Leaving any comments are optional. Usually the violations are starkly obvious and need no real commentary.

The same way you report an answer.

To the right of the question, there will be a little "flag" that turns red when you hover your cursor over it.

Click that and proceed.

The same way you report an answer. Click on the flag next to the question.

They hide it. Float your mouse over the upper right corner of the question, just past the first line. A red flag should show up. Click on that.

It's the same way you report the answer. To do this, hover your mouse to the right of the question and click on the flag for the abuse report form to appear.

You hover your cursor over the question and use the flag to the right side usually under Next.

On mobile you may need to use the desktop link to see it.
