How do I check if a wallet is connect to scammers

I recently heard about almbot, and how it is used to rank how risky a wallet is.

Quick google shows the likes of that and Eyeblock . io as all being behind a paywall.

Want to be able to check a wallet before I accept transactions with the user, anyone know of any non-paywayll solutions, ideally without sign up but I doubt that is an option.
