Reddit can restore your deleted posts. However, if people flood them with GDPR / CCPA delete requests, they may become liable for lawsuits if they don’t comply.
It sounds like their current policy is to not delete your posts even when deleting your account, but there may be grounds for legal action here.
Strongly suggest overriding all comments and posts (using something like PowerDeleteSuite) before submitting a GDPR request though. Replace it with “use kbin/lemmy” or similar.
Not sure whether it will work out but I am planning to do that before API is gone (assume ~28th of June or something).
They’d probably recover the original content, even though it is illegal for them to do so.
Don’t worry, their IPO will surely be a success after part of the community leaves + possible GDPR fines.
I did this and my comments are back.
