If you go to Uniswap right now you won't see any of these tokens. You run no risk of getting scammed by using Uniswap unless you go out of your way and manually add them.
There's also the obvious case of the scammers getting a user to actually buy the token (perhaps through spam email or "pump groups" that give explicit instructions on how to perform the swap) which I'm not saying has never happened but I do claim is more rare. Even the obviously silly scam emails do have the occasional person click on them and lose their money. The upside is that getting scammed on Uniswap is actually harder as you need to manually bypass safety features.
It looks at transactions and attempts to classify coins as scam or not.
It doesn’t make any claims about the volume in scam coins. That’s more a clickbait headline and HN thread thing.
It’s most trying to contribute an algorithm for identifying scam coins.
See the appendix for features from the transactions that they used for their algorithm.
Uniswap filters the tokens available the same modern email providers filters email. If you go looking in the spam folder and fall pray to a scam there, it is your fault, not the fault of the email provider.
I am mainly wondering about Uniswap being described as safe.
I don't know anything about the space, but it sounds like a fact and statistic that should be front and centre in peoples face all the time.
If you want to trade an unlisted token by adding the contract address manually, sure you can do that. But then it’s on you if you get scammed, like if you follow through on a solicitation from a spam email.
