I get random friend requests from accounts in discord servers that I haven’t even viewed, let alone interacted in, for years - most have some sort of “live/laugh/love” bio blurb. Maybe I’m just an antisocial hermit at this point, but I ignore every single one.

In comparison, Steam seems a lot more genuine. You can always try suggesting discord for voice chat if you’re leery of installing an unknown program just for talking to that user.
