You should never remove a fence that you do not know the purpose of. The code you don't understand was not created by an idiot! And fences do not grow spontaneously. That person was solving a problem, and that problem had requirements those requirements are what this code is at least a solution for.

If you don't understand the requirements, you likely don't understand the solution and potentially the problem either. In such circumstances it is best to either not intervene, or take the time to familiarize yourself with both the problem and the solution before you attempt to intervene.

Usually, the problem is that the code was created by an idiot. Me.
