Government's I4C database: The National Cyber Crime Reporting Portal maintains a database of know scammers which you can search using UPI ID, mobile number, email ID, social media IDs, etc. "The Central Government has introduced a new feature titled as ‘Report and Check Suspect’ on https://cybercrime.gov.in. This facility provides citizens a search option to search I4C’s repository of identifiers of cyber criminals through ‘Suspect Search’. I4C proactively identifies and blocks fake IDs used for Digital Arrest."
