Every Reddit mod post is cancer for example. So is every pinned post and automod. 99% of email. Any story about farting or buttholes or diarrhea or any other child joke about how you were unable to be in control of your butthole. I don’t want to hear it and every single day there it is. Any pro-terrorism post from jihadist groups like maga, posts from other nations pretending to be Americans, posts asking people to explain a loaded joke they understand but are trying to get more views on or spread the topic about. Any ai video any video about crypto any fake news.
There’s a lot of room for improvement. Even just detecting things like if a news article doesn’t actually contain information. It seems like we have a ton of areas we could be filtering out cancer a lot better.
