Are Alternate Steam Accounts against Terms of Service?

[A_Tree]

Of course not. Just because I own dozens of accounts, doesn’t mean I’m a rule breaker.

After all, I can have hundreds of accounts without ever creating a single character.

What on earth are they going to ban then? What exactly is my crime?

At the end of the day, it’s their game; so I’ll gladly accept any punishment they have in mind.

Once they’ve taken care of the botters, spammers, frauds; and got nothing nothing better to do, that is.

Nobody said you’ll get banned if they see you own multiple accounts and they find nothing suspicious or anything they deemed inappropriate in your logs.
Stop being stupid.
Point is if you own multiple accounts, with possibility of being able to use bots and the steam exploit, it sets you up unto the list of persons to be checked.
