A good idea might be creating some kind of portal where people can discuss different ICOs and vote is it a scam or not. I saw the thread of bitcoinwiki org here on forum and they say they're gonna implement smth like that on their portal
There must be enhancement in this forum. New features must be added so that it can cope up the latest requirements from traders and users. Like here, this case is also implementable. Scams are spreading like a jungle fire and people are getting effected by them. Hence they demoralize the peoples interest toward bitcoins. There must be awareness campaigns for catering such problems.
