EDIT2: Commenters have some valid criticisms of MBFC. Even if there are flaws, I would like to celebrate all attempts at elevating the conversations we are having.
Tbh I didn’t even mind what the bot was trying to do. I just remember opening what felt like every post and seeing dozens of lines taken up by the bot. I ended up just blocking it and cross-referencing with ground news myself.
Some of the news and politics communities added an automatic comment to new posts that linked to fact checking information, and a big portion of the community lost their minds about it. A lot of people found it biased, obtrusive, or unnecessary, and it generated a lot of conflict between the people who liked it or felt neutral. It went through many iterations based on the feedback before being removed entirely.
The entire saga was fairly disruptive and everyone is glad it's over.
