New exchanges do not have the reputation to validate a project, they are just after the profit, SO they might promote a scam project either intentionally or unintentionally.
Exactly! but even a reputable exchanges cannot filter out the right one, unless they're only after the money. IEO's reputation can still be question its just a rebrand of ICO, investors shouldn't trust it a 100%. In my opinion it is better that exchanges should look if the certain project have passed government regulations and check for redflags before deciding to list it on their platform.
