Validation Callback

Hello, I would like to know what is the purpose of the callback please.

XenForo_Option_CensorWords = Admin Template
verifyOption = ?????

The option callbacks do extra verification and processing of input values. It ensures you haven't entered something invalid or otherwise incorrect.
