To what i have seen in the facebook ads,some of the ICOs (legit ones) are still able to use the facebook paid advertising program which i suspectedly they will only restrict ICOs from joining if facebook thinkgs those projects arent legit.Facebook terms and conditions states that they wont be accepting any ICOs to use their paid advertisements but some has been using it for quite a whilte..
There are no Legit and Not Legit ICOs. These both types are not regulated by the law. Moreover, each country has it's own legislation. I also still can find ICO ad on my FB and IG feed, and this bothering me, taking to account that thay didn't allow me to promote my project and refused 3 times without getting into details.
I presume those ICO ads are old and were lanched before this new regulation.
