No I also never seen any in my circle getting their coinbase account close, the problem is that they are having strict rules about gambling what makes it more not attractable at all..
Remember, it's not just you they are worried about with drugs or gambling.
If you sell or give away coins to someone that does drugs or gambling, then you are the one to suffer.
So, before you give coins to a friend or family, just make them pinky swear to not use them for any reason other than to save them.
