I find they're doing plagiarism from a dead coin named Loligo. This is some red flags I found, if OP have another proof to say YYFI protocol is scam you need to explain it as well. DeFi is new and many fraudsters take this advantages to create scam token, but not all new project is scam if you don't have any proof. Pump and dump is normal on Altcoin.

The OP can put your post as reference - plagiarism issues. As they are not holding any presale, or private sale, we can't say that they are a scam at the moment. But looking at their roadmap, they have plans to list this in Binance.
But wonder if BNB will accept this, even just browsing their website, very generic nothing substantial here.
