I want a game on Steam that has a price tag around 50 USD but it has caught my attention that i've seen some online shop selling user accounts with games purchased in countries where prices are considerably cheaper. My question is: Does Steam allow third-party vendors to sell steam accounts? Is it likely that i will get penalized? Thanks in advance for your help.
No, Steam does not allow third-party vendors to sell Steam accounts. It is against Steam's terms of service, and if you engage in such activities, there is a possibility of getting penalized or having your account banned.
