I talked to menace and reproduced the situation which happened on Demo's report a few times. Sometimes my character rolled forward, sometimes it didn't, it heavily depended on the altitude of the jump. Since I cannot be 100% sure what happened in the exact case which led to a ban, the benefit of the doubt will go to the defendant; we don't ban for the intentions alone.
You are unbanned and your animation warning level is lowered by one. However, please, avoid using /sync at such situations in the future to keep you out of troubles.
