Anyway, I would like to say something in his defence because not stating this would mean taking actions wrongly and start useless drama. I don't know if you are aware of this or not, but the points were reset twice in the Jailbreak server because some guys were using some stuff to hack them. So basically, when I reset the points twice, I rewrote the whole vault folder, which also made some people to lack of time while they had more than 120 minutes in the server. This also means that some CT Bans issued between the date of the backup and the date in which the points were reset were basically removed so this could be the reason why Ryan could join the CT team, because as far as I know and also according to what I can see in Steam, he always plays in Steam so I wonder how would he have been capable to evade that CT ban by keeping the same SteamID.
Even though, you can still punish him for his inappropriate behaviour.
Cheers.
