I recently converted my own paid Steam game into a free game. Since then, I got two requests (one via Discord, and one via email) for a Steam key for the game.
Is this a scam, or harmful in any way (to me or to Steam)?
The only possibility I can think of is that giving a key to someone with an account without any paid games, legitimizes them (they look like a real/paying account, which unlocks ... something, I don't remember what).
The second request mentioned that "free-to-play games don't show up properly in the library," which seems like misinformation to me. I've played a number of free games on Steam, and never saw any issues with them.
