No, it is not in danger. Facebook and Twitter banned the paid advertisements of ICO projects, so projects can publish their content in this social media platforms but they cant anymore paying for promoting their posts, videos. In fact I think this will force the projects to hire more bounty hunters to advertise the project's content in this platforms, since paid ads are banned now, the unique way is the effort of their bounty participants.
I see this as quite good, as more rewards will be offered. or is it just me?
