To clarify: The “Steam profile” is something members of the “community” have. As I said, the only thing I use Steam for is to play games. I have no intention to register for their community. And – if I had registered there, I would not have wanted to post my ID in a public forum. You will have to take security and privacy more seriously unless you want to run the risk of a scandal. At the very least, you must provide a private communications channel for users to send you potentially sensitive information. If you have some place I can send you the dumps, I can pack up the whole thing and send it.
