So apparently this is a very deep rabbit hole, because now we have a third person who might own this service - Nora Puchreiner. Nora Puchreiner is… an interesting identity. Besides the links given by Jani (gyrovague.com owner) in the post, I could find her Wikipedia and Twitter accounts (both completely gone):

• https://archive.today/2024.08.22-043809/https://x.com/norapuchreiner/ (https://megalodon.jp/2026-0202-0536-35/https://archive.today:443/2024.08.22-043809/https://x.com/norapuchreiner/ in case this snapshot “suddenly” disappears), suspended by Twitter for unknown reasons.
• https://en.wikipedia.org/wiki/User:Renamed_user_ghsfrdDFG678mFG7903145lk (renamed; was “User:Nora Puchreiner”), suspended by Wikimedia Foundation’s Trust & Safety team for “impersonation” (though I have no idea who she could impersonate, because all accounts under the name “Nora Puchreiner” I could find obviously belong to one person).

I also found some AI slop post on Blogspot with creepy AI-generated images, publised in June 2021 under a “nora-puchreiner” account and perhaps describing her achievements? I can’t really make sense of what’s written in it.

UPD: also some print shop. I think all of this deserves a YouTube video by an internet oddity enjoyer…

I may be off, but this sounds pretty fishy to me. On both sides.
