That's rough. I have a similar story, in college I was in a computer lab that was free to use for everyone. Naturally some people studied there while others used the place to hang out and be a bit rambuctious. I only used that lab to hang out.

One day, I was on my PC and was talking to a friend about some niche, kinda racy topic. We were trying to access some site but the uni VPN blocked it. We tried using website VPNs in Firefox, those were blocked, Opera's VPN, didn't work either. We gave up, or so I thought.

My friend had the brilliant idea of non-consentfully taking control of the computer and trying to access the website themselves. Except, they didn't open Firefox, or open Opera, they opened Chrome. Which most people use as their default browser right? Well, except for me, who had reserved Chrome for other purposes.

Cue hundreds of tabs loading and images of fully nude women showing up in full screen. EVERYONE in that lab could have seen my screen, which was facing the hallway as well. Porn for everyone to see. The reaction times weren't fast enough and people saw.

Lesson learned: don't mess with people's computers without permission... Dude was EMBARASSED

...

He then repeated the same mistake later by opening an app on my phone, without asking, that "looked like a game". Nope, hentai app. Goddamnit man 🤦
