WHY is my instagram is following random people? HELP!!?

[Kumi]

My instagram is following random people/accounts that I don't know WITHOUT my permission.

I DON'T have my instagram connected to ANY 3rd party applications.

I changed my password and username.

Please help! It's spamming my newsfeed with random people's pictures!!

http://help.instagram.com/ <–– link to instagram's help center

http://www.wikihow.com/Contact-Instagram <–– article that should help you out even further.

The instagram's help center contains FAQ's (the answer to your problem could be in there), you can also report hacked accounts if you believe your account is being manipulated by someone else, etc. I also believe you can contact them directly from there to have help with a lot of issues.

Hope this helps!

Have a nice day!
