Research on the topic of smart contract scam

I am doing research work at a university on “Detecting scam smart contracts”. Could you tell me:

• if there is already a database with contracts that are definitely scam?
• Perhaps there are already solutions that do this?

And my personal question: how big is this problem now? In 2017 and 2022 – scam contracts were popular, now I don't really follow this topic, maybe it's not so interesting anymore.
