Facebook have it new policy pertaining to initial coins offerings 'ICOs' . The policy specifically prohibits ads that promote ICO on it platform.
The banned is due to the fact there are so many companies who are advertising ICOs that are not currently operating in good standards and faith.
In the meantime, Facebook is encouraging people to report content that violates this new policy.
What effect do you think this will have on ICOs and future of cryptocurrencies?
Facebook, as a place where there are any and all people wasn't the best place to advertise ICOs anyway, so this won't influence crowdfunding process much. Apart from the specialized forums, like Bitcointalk, there are still Reddit and Quora

But a place where you find all kinds of people would also be a place to drop information of any kind for same to go viral. My concern is, I do not know why Facebook would make policy against even shared ref links. Could it be for some good reasons? But their policies statement hasn't state vivid reasons for such policy. At least I am yet to know their reasons.
