If it interests you, upvote it. If it doesn't ... well then do not upvote it. I wouldn't mind people aggregating some info as long as it is not plagiarized. As for people being total phonies and posing as someone else ... they can at least come out and say it is a "fan page" or something like that.
But the point is that people are trying to pass off work as their own. The example I gave in my post had nothing to do with a "fan page" the poster called the girl in the photos her/his sister, Hermosa while the girl in the pictures is a famous model from Venezuela. What you say makes sense though but even then, they shouldn't be posting in #introduceyourself. A lot of people get tricked into upvoting content that is fake.
