Unless you have more proof, we can assume that you said "Say it or ban >:(" and you cropped it out or something.
Do notice the background, smart one. I wouldn't have gone to the trouble of editting the stuff out of this. Blockland's been shut down for a while now, so there's no way for me to retrieve it.
Also, since I was in Pwner's server, ask him if I've ever been admin. Without such proof, you can't pull a random threat out of your ass.
