I don’t know much about law but I assume that you can also be liable for things you don’t own.

If I rent a car I don’t own it but I’m in full control of it so I’m fully responsible if I break any laws with this car.

I think one could argue in a similar way for Xitter accounts.

Could you elaborate? I’m interested :)

There’s still a chance that a monkey will type it on the first attempt. It’s just very small.
