It would not help newbies in my opinion. There are thousands of thread with the same massage, but I did not mention less people taking part in crap bounties or yelling that an ICO is a scam and he invested 5k into this garbage, it is not going to end.
I think you are wrong for that, because in my opinion beginners aren't that stupid now, because I'm sure they probably already know a lot of junk projects and con artists in forums today, and of course they will definitely be more careful of the fraudsters who make project.
