Why has farmville been subspended

when I try to login it says it is subspended due to copywite or questionable content

A copyright issue would be if the software they're running belongs to someone else and zynga isn't authorized to use it. Questionable content could be a lot of things like it contains code that could be damaging to your machine, it is vulnerable to security issues or has content that is below Facebook's standards.

Zynga's website hasn't offered any explaination yet on what the problem is or when and if it will be corrected.
