Woopsiedaisy, thought you ment on blackhatworld. Didn't see the Instagram section.
If you search around you'll find the info. Pasted some from other threads:
There should be intervals. Minimize your activity and make sure that your comments a well-distributed between the hours of the day.
i comment 60-70 new account
100-150 by my tests. 2 year old accounts. They scaled up, though. I started 10-20 and brought it up to 150ish.
for a month account be careful, however as I tried earlier the daily limit is less than 100.
Here is my little advice hopefully worth for you :
Get hundreds of accounts and Get half no if the proxies in against of accounts get Dedicated ones.
Do some randomization instead just totally comments to make it natural and grow your main account also it will help you to grow hundreds of followers on your sub accounts also.
You can use that to promote on more big scale.
Get some software program for that task for more efficient and faster way.
Think big do big and get big
Hopefully it helps.
