Context: Voyager shows these options which results in a large amount of reports just being "Breaks community rules" with no info or reason whatsoever.
Some communities don't have specific rules, and some have several. It can be quite hard to judge why something is breaking rules. On the video's community for example people often report videos, so I have to go through the entire thing to figure out what's wrong with it (and some people post videos that are more than an hour). Sometimes content is reported because of something the people who created it did, something that is not apparent when watching the video.
