It's like this, you leave your computer for a bathroom break for example, then when you come back, someone you trust that is not into it finds the site. and asks questions that either you are or you don't answer.
it has happened to me, but not often.

I've not been caught like that but I tend to take many precautions I'll open another tab and go to google or something like that. In addition to that I'll open a second window and just go to some other site and I'll leave that one up while minimizing the other one. But I've got my own comp so I don't really need to worry about it if I'm going for any period longer than just taking a piss or getting a drink I'll close out of all Expansion related sites or porn lol.
