Yes, that was attributed to me but was in fact put in place by another player I worked with. All structures were legitimately placed without using any glitches. The two main entrances to the tower we walled in by placing pillars, walls and ceilings. Summit and his crew's mistake was building the ramp to their entrances on a foundation. This made it possible for us to easily place the pillars and all the other parts. Same thing goes for the shack outside the tower. No walls were placed inside doorways, I don't know where Summit got that idea.
Before all the fanboys pile in to rage at this post, here's why we did it:
Summit is the most notorious bandit on this server.. He and his gang KOS everyone they come across. I would be fine with that. But what's not ok is how they completely wreck each base they raid. You call us griefers? Please take a look at Summit's past stream recordings and see for yourself what a nice guy Summit is. Just before we walled them in, him and his crew
raided, destroyed and griefed a neighbouring base. It was time someone took action against them.
So to conclude: Yes, we did grief his base, no we did not abuse any glitches to do so, and yes, he had it coming.
