It's better to ignore any stranger, chance your app security settings, they won't be able to get to you unless you are the one that PM them first, strangers don't always have the best interest in mind.
It is better to ignore a stranger that is the best thing anyone can do, but what about the stranger contacting you representing a famous influencer? For example, let's take Elon Musk who is very active on his bought platform X.com. He is always trying to manipulate the crypto market with his tweets, knowing a tweet came out from his handle about a meme coin, a scammer would recreate the same product on both the Ethereum blockchain, BSC, and as of now Bitcoin blockchain.
For Ethereum and BSC, we know how to verify, but what about Bitcoin blockchain? Is there any way to cross-check a project? I am not aware of such a thing and that is the reason I have asked this question. In recent times the amount of spam created by Ordinals is beyond anyone's control and the way developers are reacting gives me a bad omen is coming soon.
