Vlad An idea I had - please forgive my poor design skills
Notice small report link beneath website ranking adjustment:

This would change the crystal ball (I'm not so sure if the large title bar makes sense here):

I suppose different reasons could be:
- Phishing
- Malware
- Scam
- Illegal content
The heuristic to actually hide results after reports is out of my wheelhouse, but I might suggest looking at uBlock's ban list in the meantime as it originally caught the malicious link in the OP.
Another idea is not hiding results but displaying a warning after some threshold.
