And yes, I know people will say block keywords and communities, but people don't understand some communities have rules and people must follow them.
I won't say all rules are valid or right, but this one just makes sense (in contrast to rules of some other communities, which outright ban certain opinions). Sometimes you don't want to hear about all the doom and gloom, and for many people, it's not good for their mental health to hear about it all the time. They know what's happening, they need some time off.
