On Tuesday, While i'm playing eggwars in team, I met a girl who gives me her Instagram, after that I told her that she musn't do this thing because there is a lot of people who only wants to do bad things.
To add on this, if I remember correctly you can set your Instagram account to private so that you first have to accept if someone wants to follow you and see your pictures. And you can remove someone that irritates you (block) and they are gone. And e-mail is very easy to make so you could keep on mailing them. Which makes it very different. I'm going to stand with NotGingerGeek and say it's not that much of a problem. With what I don't want to imply to just throw it around and hope for the best of course!Instagram is a social media platform, same as Twitter, Facebook, etc. I don't really see the problem of giving the account's name, it's nothing personal at all (not like a phone number or e-mail)
