This is a question that has been bothering me too as I have been a victim of buying into scam projects on Bounce Finance platform before. The project raised about 7500 ETH and then listed for a while on Uniswap with very poor liquidity, deleted the TG group and cut off all communications with investors. No project development. They just shared the ETH and disappeared.
This is a downside of decentralization as anyone can list a token on this platform. But as it is commonly mentioned, do your own research. I don't ignore any red flag again.
It's not only about DYOR. You should also gather more information from the official telegram group by asking the team directly about the real smartcontract that being used to issue the tokens.
Bunch of scammers were always creating shit scam erc20 tokens as they were seeing an opportunity to fool people through use the fake contract.
I have heard that kind of project that you have talked above.
