nolto.social is vibe coded.
In their documentation at https://github.com/Jtensetti/fediverse-career-nexus/blob/main/README.md the first thing it says is "Built with ❤️ on Lovable.dev" https://lovable.dev/ a vibe coding service. Followed by extensive emoji use.
You can see in their git commits, the author is nearly always "lovable-dev[bot]" https://github.com/Jtensetti/fediverse-career-nexus/commits/main/
Also on their LLM-written home page they claim to federate with everything, which is impossible. Believe me, I have tried.
