The EU has the GDPR and California has the CCPA that both give people in these places the legal right to have their data removed from sites upon request. If they end up putting your stuff back up or reverting edited comments/posts back to their original form, you can submit a notice through these organizations to bring the law into it and either make it illegal for Reddit to restore your stuff or at the very least force them to pour money into legal disputes to argue to keep it against government enforcement.
Other states/areas may have similar internet privacy laws in place so check to see if this exists where you are!
