In terms of scamming projects tron tends to deal with scam projects running on its blockchain ,why can't ethereum do the same??
Who will be deciding whether a project is scam or not ? A separate team ? I guess that will lead to more centralization. A true decentralized system will not go for censoring and leave everything to consensus like people will decide on their own. There are both pros and cons if tron keep doing that and I am not sure what will be the consequences in long term. I guess it may help them to attract more investors as scammy projects are being moderated.
