I got accounts that have 10-20 sec delays, and like 2000 photos a day.
I also got accounts that have 240-420 second delays and like 200 photos a day.
Guys, it's all about what your account has been doing for the past 3 months. If you didn't like much and then start liking every 60 seconds, and 800 photos in 24 hours; guess what? Instagram may very well temp ban or delete your account.
Start slow, and then play around. If you get hit, you know that's your limit. No two accounts are the same.
