It should take 30 days for your data to be scrapped after an account deletion: https://github.com/LemmyNet/lemmy/issues/2977

Thank you!
This isn’t easy to do yourself: thing is, the way you identified yourself as being “you”, an asymmetric cryptographic key pair associated with your account, got deleted when you removed your account.
If your posts and comments don’t contain any personally identifiable information (that is: no-one can tell it was you who made them) I’d just let it be. Otherwise this is going to be difficult.
Addenum:
Even my profile picture and banner got reinstated.
Do I request to GDPR my data?
You can try, but the reality is all of your activity gets replicated to every instance. You should assume that it's permanently out there.
There was a discussion about GDPR on mastodon github, and they seemed to conclude that GDPR does not apply to natural persons, which includes most instance admins who aren't corporations or any entities, but just random people not profiting from anything.
Not sure how valid, since they aren't lawyers.
That doesn't sound right. But then again, like someone else already said: If they aren't in the EU and don't have dealings with them (because they aren't large companies), who is going to enforce it?
