Previously this week, Ender logged on and said "hello banesgreifer" (Something along the lines of that) and Banes responded with "Shutup endergriefer" and followed with "Port knows I did" and "I only placed blocks".

So this means Banes lied about Port knowing and only PLACING blocks. The screenshots are below (I had to break the blocks to recreate the damage as Port repaired it - But he approved of this):
I intentionally broke it here to recreate the damage (it's fixed now):
