There are two possibilities: Either it's really a hack or it's a felonious attempt to manipulate an election. Or it's both -- a hack of personal private photos and also fake emails feloniously manipulating an election. Either way, a ban is appropriate.

Saying "if it's true, it's ban able for X" without out bothering to say that obviously it's bannable if it's false, isn't saying it's true. How could Twitter even know?
