I know I see the world a lot more straightforward, but - why wouldn't you? You don't come to random strangers and expect them to act as if they care about you, let alone expect that they should (beyond general human decency, that is). Why are famous people any different?

Now, I know what might be said about famous people. They're idolized, idealized - to the point where them acting like a normal human being is considered odd. You don't ever think that Bruce Willis has to shit sometimes, or that Rihanna has to wax her pubic hair - and yet, they do. They, too, have to have friends, eat, sleep, be passionate about something; sometimes cry, laugh, fall ill or be in a better mood than usual.

YouTubers have a different sort of fame. Unlike the film stars or pop singers, they're relatable; they're "our guys" who just happened to have made it to the top. We want to get to know them both because they're relatable and because they're famous. When Markiplier said that he really likes the Russian portion of his fandom and even entertains a thought of coming to Russia, I immediately thought "Oh, man! Wouldn't that be cool to meet him and show him the place? We would spend some time together, and that would be awesome!". He's a cool guy... who just happened to be extremely popular (14 million subscribers are nothing to joke about).

But here's the thing. What you, as a devoted fan, don't realize is that a) you're not the only one like that, b) the person you quietly worship is just a regular person (though with the discipline and the passion like few else display), c) you're creepy when you do what PewDiePie talks about. For you, a devoted fan, what you do is just show your idol your admiration, let them know that you like them very much. In itself, it's admirable to not hold such a level of appreciation back. However, when it comes to invasion of privacy, what you do is not okay. Spying on next-door folks isn't - why should it be different for someone famous?
