I do not know for how long these scammers will keep sucking the innocent traders and investors who are buying the similar coins thinking of some other coin.
There should be some mechanism to stop such scammers. Maybe uniswap should start officially listing each coin with official ticker. Otherwise the fraud will continue.
As soon as Uniswap starts checking and regulating DeFi projects that are traded there, it will immediately cease to be a decentralized exchange. It is obvious that every trader should review the contract of the token before to buy it. In this case, scammers will have fewer opportunities to deceive you.
