On every submission, you will find a three-dot icon. By clicking this, and then clicking report, you can report the submission to the appropriate channel's moderators.
This will open a modal, which will allow you to select a reason for reporting. These are:
- The post is spam.
- The post breaks the channel's rules.
- The post breaks the site's rules.
- It's harassing me or someone I know.
- Other.
You can then give additional information as to why the post is being reported.
Once this is done, click submit to send the report.
