Part of the problem is that Twitter and Facebook deliberately traded away effective moderation in the pursuit of scale. They are not just bad at moderation, they explicitly oppose it. Remember how Twitter gave Trump exemption from their own rules from 2017 thru 2021? They called it the World Leaders Policy, as in, "these world leaders provide so much value to our platform that we are going to give them a pass on our rules in the name of free speech". If I remember correctly, this even extended to DMCA 512 takedowns, which is an absolutely stupid level of risk to take on to protect a handful of users. The Mudge disclosure also revealed that several Twitter admins - as in, people with control over all the servers and databases - are actually foreign agents of India or China's current governments. This is absolutely ludicrous levels of risk to take on for any company, but social media is so addicted to scale that this was deemed acceptable. So even if Twitter were to enforce identity verification on everyone, they would still let the trolls through. Because the whole org is compromised and their incentives are to compromise themselves at every step.
