Sorry for the late response, haven't slept in 28 hours and have been doing college work all day.
It is true that LEO massed. I'm not sure what was up with him at the time but he was coming off as very mingey. Essentially, he ran up to my base, which has a "kos if inside" textscreen up, and started shooting people right outside my base. He even said over his mic "What, there's a KOS sign up. It means I can kill on site" or something along those lines. I was in teamspeak with Bhudda, Blocky, and others and did say he should be banned for mass. I didn't explicitly say to ban him on the spot though. Would it have been nice if one of us reported it? Yea. However, it was evident that he was intentionally massing and didn't appear to care about what he was doing at the time. So that's a -1 from me dawg.
