Especially if you're a girl. No sexism or anything, but girls are more vulnerable than men. This is not a sexist comment, but I am just stating that if you're a "cute" girl and a male is attracted to you, they'll try to get your IP then find you since they already know what you look like. I've never heard of a girl stalking someone after getting their IP. But it DOES go for men too. So don't make your profile picture a picture of your face, it's irrelevant and can be dangerous.
