I think, you do not have to bother bother, Promotions of this kind is pretty good. ICO is doing this kind of thing just to attract and get more investors. However, if you are a wise and intelligent bitcoiner, you will not be easy to believe in this kind of advertising.
This is called an ad in my opinion. When you have your own product, you tend to promote your product and give negative feedback to your peers.
so, yes you do not have to worry ok.
