Might be a good thing so those scam projects wont have any chance to get promoted easily,it means these scammers will have less people to target because im sure most of the ICO scam victims are from the google/youtube and in facebook advertisements.So to stop these scammers from stealing people's money facebook and google needs to exclude these ICOs for good.
The entire history of the stock market is full of similar stories. Hardly any scam involving crypto is unique to crypto. Crypto just makes scamming much easier since transactions are irreversible but most of the actual scams are recycled from the past.
