It definitely should be possible to at least anonymize some comments (disconnect from the main account). Norms are changing so fast an innocent joke made in 2015 could be enough to get someone cancelled, and the retroactive norms are only getting stricter (I wonder what's acceptable today that's going to be enough to cancel people in 2025?).

I imagine many people who posted under their real identity, or revealed it, are now regretting it for this reason.
