The only time instagram is inappropriate is when you post inappropriate pictures and stuff like that. instagram is nice but sometimes you can't trust cause somebody might try and get personal info and stuff like that. yes instagram is inappropriate. but that doesn't mean you have to get of it. if you see somebody posting stupidness block that B I T C H
It's not really inappropriate, there is swearing in pictures and the comments but if you just follow like your friends and make your account private u only see good stuff and no one that you don't know can follow you.
I wouldn't say instagram is bad it's just there r bad people on it so if your account is private u can look at some ones profile before you let them follow you and if they have a bad account block them
