Too many ico appeared recently. facebook ban out. I think that's a good decision for cryptop. will limit existing Scam ICO.
Of course, that is great. Scammers have been using that a lot and Facebook has done a good job by banning them out. Very soon scam ICOs will be no more because, anti-scam campaigns are coming out soon.
Facebook banned the advertisement of cryptocurrencies, bitcoin, ICOs and many more but they can't stop all people using them or promoting them by sharing an article or so.
The campaigns that we see in the bounties about the social media campaigns are great enough but also spammy and are completely legit even though I haven't joined ever.
