Old Twitter suspended and suppressed right-leaning accounts 10 times more than left-leaning accounts.

Factual claim (19 Mar 2024) that pre-Musk Twitter suspended and suppressed right-leaning accounts about 10 times more than left-leaning ones. True: credible data (internal Twitter data, the Twitter Files, or peer-reviewed or systematic studies) show roughly a 10:1 ratio (about 8–12x) of suspensions/suppression of right- vs left-leaning accounts. Mostly true: the evidence shows a large disparity of the same order (e.g. 6–15x). Mixed: a clear disparity exists but is much smaller than 10x (e.g. 2–5x), or applies only to suspensions or only to suppression. Mostly false: there is some disparity in raw numbers, but the evidence attributes it to differences in rule-breaking behaviour or it is far below 10x, so the claim distorts a real pattern; or no data supports the 10x figure (unproven). False: systematic evidence shows no disparity, or the reverse.

   “During that period, Twitter suspended 7.7 percent of the Democrats. In contrast, the platform suspended 35.6 percent of the Republicans — a more-than-fourfold difference.”

   “Our research found that accounts sharing pro-Trump or conservative hashtags were suspended at a significantly higher rate than those sharing pro-Biden or liberal hashtags—they were about 4.4 times more likely to be suspended.”

   “For example, suspending users with a bot score above 0.5 would lead to 14.2 times more users who shared Trump hashtags getting suspended compared with users who shared Biden hashtags”

   “An internal study Twitter conducted in 2018 found its algorithms favored the political right.”

The evidence shows a real disparity in suspensions, but at roughly 4–4.6x rather than 10x: about 35.6% of Republican-linked accounts were suspended versus 7.7% of Democratic-linked ones (E1), and accounts sharing pro-Trump hashtags were about 4.4 times more likely to be suspended (E2). The Nature study (E3), titled 'Differences in misinformation sharing can lead to politically asymmetric sanctions', indicates that differences in misinformation sharing can lead to such gaps. Its 14.2x figure is a simulation, not an observed suspension rate. On suppression, the Twitter Files brief reports that an internal 2018 Twitter study found its algorithms favoured the political right (E4), which does not support that part of the claim.
