They added a line to the bot that includes Wikipedia’s stance on a source. And Wikipedia doesn’t consider MBFC to be reliable, so the bot reports that.
If you scroll below that, MBFC rates themselves as maximally reliable, which I’m sure is based off of a rigorous and completely neutral assessment.
Edit: although, reading the links in question they don’t seem to correspond to what the bot is saying. Perhaps this is some sort of mistake in how it was coded.
It’s not a mistake, just confusing UX. The text in question comes from https://en.wikipedia.org/wiki/MBFC
It doesn’t though. Or at least, I didn’t see anything resembling that on that page. If you can find it, let me know. It’s possible I missed it.
sorry, https://en.wikipedia.org/wiki/WP:MBFC. that’s what i get for attempting type a link out on mobile
