Yeah, no wonder it was removed - entirely without citation and low relevance. To be honest, the existing line “…been criticised for its methodology” is on shaky ground, I checked the citation and I would not characterise it as a critique:
“Media Bias/Fact Check is a widely cited source for news stories and even studies about misinformation, despite the fact that its method is in no way scientific.”
That is the entirety of what the source says, it doesn’t go on to mention it more in later paragraphs, just that one sentence.
CNN’s own source for that claim is a single tweet with no reactions to it whatsoever, which doesn’t feel very iron-clad to me.
Considering the massive incentive for powerful companies and individuals to cast doubt on the veracity of media bias/fact check, it seems irresponsible to interpret the source in that way and to spread that claim as though it’s entirely watertight.
Can I ask, why did you even post your original reply? Did you do your own fact check in January, see that paragraph, and decide to share it to discourage people from trusting the fact-checker?
