I don't see any possibility of money laundering through crypto advertisements. I mean what makes you think that crypto ads can get your money laundered! The crypto advert is meant for publishing different project ideas amongst the targeted people who are interested in spending money into these projects. These projects are mostly related to the different utility tokens, automobile industry or even healthcare projects etc. If you think that by any means this is money laundering then I dont think you have understood the concept completely. Both are different things in first place.
