There NEEDS to be a crash course on greifers

Two of my Eve towns were griefed, and the line was ended, in less than thirty minutes by the same person. The amount of times that towns are griefed and new players don’t understand how to banish them in a timely manner, or even at all, is absurd. People need to be taught that you can hover over an item to see that its state was changed, ex: a pen of butchered sheep, or that you can banish from empty bear caves. The same greifers continue to go around and ending lines over and over again without a red B to their name because the influx of new players don’t even understand the concept of banishment. It’s so frustrating.
