I don't know where you are from, but in Europe fact checker are actually only face up (and not too much) blogs, Facebook groups, and other similar media that makes hoaxes. Their news are like "that politician said that and this is false due to this, this, and this", "microwaving your phone won't charge it", or "vaccines won't give you 5G".

Heck, I read in some of them about how some important people done really bad things in the past, all with valid evidence from trusted sources, and no media faced them up.
