Can I look for love on pictochat like I used to?
That depends. Why did you use to do that?
Because it's fun and I can talk to people outside my school
I hear you reasoning, but it is bad to look for love in a place for kids. You should consider hanging out with people more your age in a club or a hobby group. Otherwise you are setting  yourself up for disappointement and criticism.
But I'm sure pictochat is the only place I can find love.
It is not a good place to look for love since the age group using it is not for you. You should find other places where you can meet people who are more age appropriate.
