I'm not sure it's coinbase's responsibility to tell users not to run with scissors. Anyone who thinks sending money to random links they see on the internet that are promising to send them more money back for free probably shouldn't be entrusted with managing money.
What should a founder do? Focus on their product, the better they become more scamers will attract, but is for the user to use some basic logic.
Otherwise, should they tell people that there is no such thing as Nigerian Prince? Because Nigeria is a Republic but some people don't even check the basics, they tend to just refuse their responsibility.
I think a good solution would be to allow users to flag a wallet interaction as a scam (akin to a down vote). Then, after enough votes, you could get a warning analogous to what Safari does when you are about to go to a known scam website.
People here forget that the average person (especially as they age) will at some point fall for a scam. Insurance companies are starting to recognize that, because as you approach old age and death, apparently the mind gets more trusting of strangers to reduce mental load.
If this system existed it would immediately cause all scammers that aren't already doing it to make a new wallet address for each 'lead' and make a reputation system worthless. I would be very surprised if this wasn't already common practice.
