@LEFT4GABEN I
assume that they are allowed, to an exception. I have about three alternative accounts on about three different PCs that have Steam with Garry's Mod, but besides the point. If you are using an alternative account for role-playing reasons and aren't breaking any rules, then you'll be fine. If you are playing on one PC and another PC at the same time and doing item transfers, etc, then you will be busted and will be shunned/banned on both accounts. Just don't use your alternative accounts for any misuse, or consequences will follow. I know some communities that ban people that use alternative accounts, but that is just a completely absurd idea to an extent, of course. Players should have a right to use different accounts and not giving them that right is foolish. If abuse is shown on any account, whatsoever, then it will be fixed, simple.
