You are right, I see that they are beginning to abuse the IEO concept of Binance and like you said, all these small unpopular exchanges wants to also get involve with IEO too when they are not ready to do due diligent like Binance. What most of those exchanges just do is to accept the project without investigating the project, and if they do that, what is then the difference between the projects being counted as ICO.

I count all the project that I see announced as IEO on all these small exchanges as scam projects because any reputable and reliable IEO will go for exchanges that are reputable too like Binance and other great exchanges that are the main actors in IEO. This is why we have to also make sure too those projects called IEO that we choose to be interested in should be from Binance.
