Oh there certainly are instances of Steam closing accounts. Anything which breaks the Steam TOS can result in your account being disabled - this is very different from a VAC ban as it means you can't even play single player. Reversed payments, fraud, sales of accounts, these are just a few things that can have your account disabled altogether. Let's set up a hypothetical example. You have an employee who wants something to do during his lunch break, so he buys a low-spec game on Steam - something like Half Life 1 maybe. He pays for it using his wife's credit card, and when she sees an unexpected transaction to an unknown place she phones the bank and reports it as fraud - yes, she should've checked with him but didn't. The bank reverses the charge and your account gets flagged and disabled for fraud. Sorry, your WORK account. Another point, Steam doesn't allow for account sharing at all so each employee would have to have his own Steam account with products registered to him which would remain his after he leaves the company? Each new employee would need to have software purchased for him? If you're caught sharing a Steam account it can be disabled... Stick to games, Steam. It's what you're awesome at doing, but I'll buy my software elsewhere.
