There is right to be forgotten for EU, And probably state by state laws in the US. but it might be too little too late.

I thought this too at the time. I ran the scripts, check my profile to make sure they were gone, then deleted my account. Went back the next day an a lot of my posts were back. And I couldn’t delete them anymore since I killed the account.

But I just checked, and they are gone. I can search google for my old username, and just references to my u/ by others is seen.

You might want to check again; I think there was some cache or mirroring that the deletes took a long time to propagate through.
