They are long, complicated, and from what I've seen and read they're almost impossible to trigger unless you're posting things that are outright illegal - child porn, terrorist stuff, snuff films... - and generally accepted as such. You can say "black people are stupid" as much as you like as long as you're polite. Alex Jones gets close to getting banned from time to time by having "community strikes" against him, but I think there are a time limit - four in three-months I think. You're not supposed to suggest this, but I would say do report stuff. If you think it's breaking the community rules - hate speech is the most likely - then report them. I doubt it'll make much difference. YouTube, like the social media companies, have managed to get themselves regulated as platforms not publishers, so they're not really responsible for what goes up. The DCMS committee wants to change that I think.
