Now that Oobekr/Warlord were officially given a warning, the next time will be off with their nuts. Although I doubt they'll have this issue come up again - whether they were the multi or not.
I would also mention that this isn't the first multi engagement performed, there's been a few others. Sometimes we'll handle them through email, sometimes through in-game messaging. This one was uniquely brought to the forum to try get a confession - which did help a lot since L19 worked diligently to try uncovering who the multi was. Ultimately, I feel this punishment is good enough, as we don't lose real players from too harsh a punishment, and they know they're obligated to self-report suspicious activity (or risk being labeled a multi) going forward.
