You might need to post multiple answers because you have reached the maximum answer size and still have more to say as evidenced in [this Q&A](https://serverfault.com/q/49765/37681) 

I have posted a question with two different answers to make a [simple ballot](https://meta.serverfault.com/q/8410/37681) here on Meta. 

But those are exceptions and not the rule. 

I think as moderator we even have the ability to merge multiple answers to prevent people from trying to rig the system in the manner you envision.
