I get the reasoning, but I don't see this applied to some platforms. Reddit and Discord allow you to both delete and edit older comments, and there's no limits on how far back you can go (so you can, if you wanted, edit or delete your entire history).

Under the GDPR a subject is allowed full erasure rights. If I say I want you to delete my content from x date to y date, or a particular post, or everything entirely then that shouldn't be an issue. A request may be bothersome, but that's what happens when you don't offer that functionality natively.

I noticed a few days back you didn't like it when a user made a new account, except with the internet these days and how everything is archived for all time, throwaway's are the only option. Building a comment history is extremely dangerous, especially when you might forget what details you may have posted or how meta-data can leak through (such as what subs you post in, any details you posted that could identify you etc).

You can't have it both ways: no to multiple accounts and also no to control over your data. I might have 50 accounts, dislike it? Give me proper control over my comments. (to be honest, it may just be worth making a new account for every comment for maximum privacy, it's extreme, but it's a viable option).

If I want to delete them, that's my choice to freely make. Your thoughts or concerns are not relevant to me, thankfully, the GDPR agrees.

I think you must have misunderstood whatever the moderation comment was, there's no prohibition on throwaway or multiple accounts. Just against using them to violate the site guidelines which is a different thing.
