Can you imagine how much additional traffic they got after all of the most popular file hosts closed down? It's not easy to handle multiple times the traffic from one day to another, guys!
So keep patient, I'm sure BitShare has only a temporary problem, two days ago they made some payments so they are not willing to go like some others...

If you may have a look on the traffic boost for BitShare, go to Alexa and please, stfu with your allegations!
