My experience on Ask.Fm is:
Ask.Fm is an amazing place, I made a lot of friends here! It's a great place to express your feelings about certain things that you don't really express in real life. You can flaunt your pictures and get/give rates and judge people openly LOL. In addition to that, you can send gifts and wishing someone on his/her birthday has become so easy. It's a great social site but all this good comes with bad too. For example,
Most people here are pretentious.
Some of them are so proud, they'd leave no reason to insult you.
People need a lot of attention here.
People ask for likes but when you go to their profiles there's nothing worth liking.
The only good answers you get are on Khadija Abbas & Ghalib Khalil's profile.
There are a lot of bullies here.
Most questions by anons are either rude or beg for likes.
Every loser I've ever known is a superstar on Ask.Fm
There's my experience on Ask.Fm!
