There are many of such projects that are being run on some exchanges like latoken and its similar sister sites. These day, no due diligence is done again when IEOs started. What exchanges are best at is that they charge huge  and conduct the ieo as far as they pay the said amount to them. This shouldn't have been the case because some projects that scammed its members during the ICO time are coming back to pay to conduct IEOs to get the IEO season's money.
