Hey nostr:npub16g4umvwj2pduqc8kt2rv6heq2vhvtulyrsr2a20d4suldwnkl4hquekv4h , what's this? This is one of my first prompts at ppq.ai. Deleted a long time ago. Yesterday they showed up about 50 times again in my history. Shouldn't something that's deleted actually stay deleted in a privacy-friendly service?
