My friend and I wanted to do some roleplaying so we thought we'd use the "corruption" in the southern wilds for the base of our roleplay, so we followed the corruption to what we thought was the source. It was a "animated" bedrock tower surrounded by swirling corruption, we fought our way to the top to destroy the eyes (glowstone) and heart(obsidian) of the "monolith" like structure and after we were done, I got banned for griefing an admins work. Sorry, but I didn't realize that was off limits as the blocks were able to be broken.
