Do not respond to direct messages from people who claim to be founders, celebrities or influencers associated with a particular NFT project. It is common knowledge in the NFT space that project teams will never DM you first. Thus, it is best to assume they are scammers unless you send them a message first or reach an agreement on a public Twitter thread or Discord channel.
Finally, you should note that staying informed is the best way to protect yourself from NFT scams. NFT scammers are constantly innovating and coming up with new schemes. Therefore, it is essential to learn from the experiences of other NFT enthusiasts to avoid falling for such scams.
