I think a little pop-up for clicking on the downvote to select the reason for rejection would simplify approval process—and educate participants on what they are actually supposed to be doing. Options for rejection are:
- violates terms of service
Definitely also a good idea!
Here are some more or less obvious ones perhaps:
- Explicitly sexual
- Spam (is it even possible to spam niche suggestions..?)
- Hateful (Nazi or KKK related, etc)
