Tell me why I'm wrong about this ICO promotion strategy...

So, recently many ICOs have have their marketing team reach out to me through Twitter, telegram, and LinkedIn asking me if I have participated in their ICO or want too. When I respond that I can't because of US Securities laws, here's the top responses: (1) "yes you can, it's not a security; (2) it's a great investment with huge upside; and (3) essentially anything else they can say to get me to buy their product despite my reservations.

So I ask. Do these projects simply not care? Do they not realize that they are violating other laws for soliciting investment? Are they just taking a gamble?

I've got no idea why some ICO are so persistent about it either.

What are your thoughts?
