every single day ICO projects always appear with their respective advantages. but in fact, many are experiencing failure in the end. they just waste time and spend money to advertise? how about you're opinion 
It's not rude for every people try to make their life better same as the icos. Many people create ico to expand their work or trying to collect funding to globalise their products and services. Not all of them failure.a lot of icos getting success collecting funding and create a good product to sell, and then they sell their token with the high price too so its not waste time to advertise and trying. To stop icos i think there is no one can, except the crypto world crush and there is no bitcoin more.
