Name: Mr.Rat Man
SteamID: STEAM_0:1:29872786
Proof: Watched him try to speed hack on Combine. He made it to the top, of the first part, faster than everyone even while walking through the giant slow trap at the beginning. (Took him about 5 seconds)
Other(optional): Banned already, need extended.
Name:
PurpleSteamID: STEAM_0:1:42171344
Proof: Multiple extremely low records on Grassy.
Other(optional): Banned already, need extended.
Edit: He may have not been the Melon on Sky, however, I joined the server when I saw him hacking on Grassy and he left, but he was recorded on my Steam's recently played with list as being played with at that time (I had not played with him before that).
Murasaki and
Melon may be involved somehow. If Purple doesn't match either record then it has to be these two.
