I agree ^.
If you navigate to instagram.com on a web browser you might be greeted with the online sign up form. (The screen comes and goes while IG are messing with the feature)
Obv. you need to be signed out of any accounts on your laptop and I'd change the IP address by rebooting your router every 3 accounts to just mix things up.
You can upload a profile pic (You only get once chance)
Write a Bio
Edit name etc etc
I have created 25 accounts this way. While the sign up screen is working you can create accounts fairly quickly...
