I strongly suggest improving the town wall. making it thicker and perhaps lava filled or just plain thick enough that the griefer gets auto-kicked before total breach. I personally went around the town wall yesterday and found about 3 different spots blown open by what seemed to be creepers. with dates going back to about 2-3 weeks ago. So a routine check for holes might help to.
With all the damaged terrain maybe you could have a moat of some sort.
Just banning people from your town cannot keep them out 100% but improving your securities can increase the odds in your favor.
