Vanguard takes screenshots of your PC every time you play a game. Every time you play a game a function is called to screenshot your PC’s screen, in case Vanguard thinks you might have something suspicious, it screenshots your ENTIRE PC screen (all monitors).
Edit: Not trying to spread false info this was shared to me via a friend and there is other data to back up that this is real https://www.unknowncheats.me/forum/anti-cheat-bypass/634974-vanguard-taking-screenshot-pc.html

Okay, do YOU honestly think Riot is taking screenshots from regular players and sending them to their servers?
Or is it more likely that this is propaganda stemming from people who make money selling cheats (and those who are convinced by those rumors)?
Points at everything riot has ever done
Yes yes I think they do
