I have blocked 357 accounts that sent a random friend invite, where 302 of it were automated. I do have some stuff on my Team Fortress 2/CS2 inventory which attracts all sorts of scammers and bots, even though I’ve stopped playing both games for quite some time.

With that said, I’m cool with random invites from real people. There are lots of games where you can use more people to play with, regardless of how close you are.
