!event.isCanceled() no working?

So I have a plugin I developed and I use it for anti griefing and I noticed that on WorldGuard protected area's it still detects the blocks being broken meaning I can't ban them because I don't have proof because it wasn't actually destroyed. And it automatically demotes people who use nuker. So if they use nuker ina world guard area it demotes them and I can't ban them and they leave because they know "Oh shit I has to much heat!". I used for the BlockBreak event

Code:

    if( !event.isCancelled() )
    

and the code still runs. Any help?

NVM I think I found out the problem. Worldguard has it's own fuckery I have to deal with :L

thats saying if the event isnt cancelled. if u want to call it on event cancel delete the !

 

I know what I put :L I have the code I want to execute if it's not canceled inside the if statement. WorldGuard has it's own API crap I have to deal with.

 

Also @EventHandler(priority = EventPriority.MONITOR, ignoreCancelled = true)
