I witnessed Soundbyte lag a bit as he was sprinting in the new trading post building. I visibly saw him sprinting, laggily hault, particles still appearing at his feet, and suddenly mini-teleport a few meters across the room, still sprinting.
For greater clarity: Soundy doesn't hack, yet was standing still with particles appearing at his feet for a short moment.
We declared Rainy not guilty because of the possibility that a little lag skip could cause it. I personally witnessed such a thing with Sound.
For this reason, I vote that Rainy is not guilty.
Edit: UNLESS, Kovos's theory is right, and Rainy was literally just standing there for a long time with particles at his feet, Tr0ll_, was he?
