To me this isn't even worth checking out. I don't keep anything on coinbase and if they want to do that that's their business because there are no regulations on Bitcoin in that particular realm. So the fact is if you want to keep your coins on there and put them at risk that's your choice. Its been advised many times to remove your money from the online wallets before Aug 1.
If they want to play games and if this is an actual real event and not just somebody on the phone trying to get attention, then rip your coins out of there and put them back later after August 1st. They want to play games give them nothing to play with.
