Today ICO numbers becomes bigger, in connection with that, Bounty Hunters also becomes higher in numbers. Last time I was thinking about the social media bounty campaign which is my friend is joining. He has more than 30 ICOs bounty campaign in his list. He posted 30 or more in a day to met the requirements of an ICO.
Here is my question, is it possible that the facebook account of my friend will be ban in the future? When the facebook developers becomes aware on this activity. Will his activity on facebook will fall as a spam?

PS: Please! my apology of my English, Im working on it.

Yes it is possible that your friend's account would be banned if he/she is posting 30 post per day. It will automatically ban once facebook security detect a suspicious activity in spamming. Better post 1-2 hours interval to avoid this ban.
