There is the burden of proof, to not completely decimate someones life on the word of c tier journalists.
Oh. Well, if you're just gonna jump to this shit, that's disappointing.
I'm assuming rather than some "c tier journalists" (I literally don't know who you're referring to?) they trust 1. their friends, who are among the accusers* and people who were tweeting about it due to other people having talked to them about it, and 2. the other people who came to them privately with their stories for what they're writing about it currently. But sure, whatever, the words of c tier journalists.
*(I feel like "accusers" sounds kinda weird/mean to them; I'm not sure how else to word that other than "victims" though, and not everyone wants to use that label for themselves)
