Hey, Wraith from Finland just told me that some scammer is pretending to be from Steam Unpowered and is sending out links to malicious software or some other scam.
Please watch out for this user: Atomic Storm. I’ve reported that profile and advise you to do the same.
Atomic Storm: Hey! We held a competition in the group steamunpowered! Prizes – {LINK REMOVED}
Atomic Storm: You have been selected one of 10 random winners!
Atomic Storm: Choose any 5 item from the list on the screen.
This person is not from Steam Unpowered so please add your friends carefully! If you ever win anything on SU I will contact you directly via e-mail or my Steam account.
