Our side of politics claims that there is social media bias against conservatives. Well, the other side have rolled out their social scientists to challenge this:

“Motivated by the long-running argument in Washington, DC, computer scientists at Northeastern University decided to investigate political bias in YouTube's comment moderation. The team analyzed 84,068 comments on 258 YouTube videos. At first glance, the team found that comments on right-leaning videos seemed more heavily moderated than those on left-leaning ones. But when the researchers also accounted for factors such as the prevalence of hate speech and misinformation, they found no differences between comment moderation on right- and left-leaning videos. "There is no political censorship," said Christo Wilson, one of the co-authors and associate professor at Northeastern University. "In fact, YouTube appears to just be enforcing their policies against hate speech, which is what they say they're doing." Wilson's collaborators on the paper were graduate students Shan Jiang and Ronald Robertson. To check for political bias in the way comments were moderated, the team had to know whether a video was right- or left-leaning, whether it contained misinformation or hate speech, and which of its comments were moderated over time. From fact-checking websites Snopes and PolitiFact, the scientists were able to get a set of YouTube videos that had been labelled true or false. Then, by scanning the comments on those videos twice, six months apart, they could tell which ones had been taken down. They also used natural language processing to identify hate speech in the comments. To assign their YouTube videos left or right scores, the team made use of an unrelated set of voter records. They checked the voters' Twitter profiles to see which videos were shared by Democrats and Republicans and assigned partisanship scores accordingly.
