Does anyone know of any less-biased/corrupt news communities?
Lemmyverse.net has a searchable list of communities spanning the whole of the Threadiverse, and it’s probably the best tool to find an existing community that fits whatever one is looking for.
If a community doesn’t yet exist that has rules/moderation procedures that fit your preferences, then you can start one and aim to make it an appealing place to attract users. I’d pay attention to the instance rules when you set it up to make sure that it’s in line with whatever the instance permits.
