If the bannings continue on a regular basis, then no, there isnt a problem. But likely this will turn into Lineage 2, where they come and go every couple of months with ban waves, and eventually the periods between bannings get longer and longer. NCSoft has a reputation for their actions for a reason.

On another note, I am reading a LOT of innocent players being banned with this move unfortunately. I left the game a month ago now, and I dont miss it honestly anyway. Nothing more frustrating then watching cheaters prosper and my reports getting ignored.
