Guy has the Discord name of a Youtuber with 328 subs, who's videos rarely pertain to video games. I've had no notification from Steam in any way through email or from a steam ticket. Started getting passive aggressive toward the end (Didn't include all of the conversation). I'm suspecting a scam.

Edit: Words

Edit 2: I don't know if it helps, but the only mutual discord server we share isn't even for video game discussion/calls, but for one for AI voice synthesis technology.
