From what I researched today, Poloniex has seriously created some insane terms and conditions!
They have the 'right' to change their terms when as and when they please, but also at short notice. The notice can be given by email - with terms coming into effect immediately.
This means that if you haven't checked your email for a day, you will not even know if these terms/conditions currently exist.
Quite... unreasonable terms... I guess people will go to other exchanges?
