The Solana Mixer team has created and will be maintaining a directory of scam sites on Solana. It has been made to keep track of malicious URLs so we can make Solana a more secure and safe space.
You can view the list with short descriptions on our website or view the raw list on our github.
You can submit sites using our contact form on our website or you can private message me here on the Solana forums. The list will be constantly updated as we find more websites.
