There rarely is accountability (especially at a reputational level) nor the self-admittance of error in re the multitude of false (often major) claims over the years. That goes for posters who continue to push the debunked claims after they have been debunked or simply moving on to other feel-good but false claims.
Debunking things or simply disagreeing on things that many people WANT to be true, things that align with their wishes, is a thankless task, as people do not take well to having a personal ox gored.
2 perfect examples are
1. The continuing 'This Will Hold'-style BlueAnon 2024 election denialism (with the denialist claims also being an attack on Biden and Harris, as people making the claims are, by their own logic, saying that Biden and Harris were either too inept to stop it despite having thousands of legal and election professionals in their resource quiver, and/or were in on the steal themselves).
and then
2. The tortured-logic-employing and ultimately false claims and attempts to try and paint the Charlie Kirk assassin (Tyler Robinson) as a RW MAGAt.
