Instagram script for following from comments

Hi!
Is it possible to have a script in iMacros or another program which is working on Instagram and following people who commented somebody's photo? For example it goes to somebody's profile and than it clicks on the first photo and following people from comments in sequence. Than if it detects that comments under photo ended, script will click on the second photo and will be doing the same. Is it possible in iMacros or if not in other pogram? Maybe one of you have a script like this?
I greet and please help.

Hire a freelancer for this.
Possible with iMacros

thanks for the reply. I presume that iMacros can not detect if it is following user for example seond time. I rememberd that I saw a chrome extension where it's following user from comments and likes, but now it is paid. This extension is detecting if I was following a user before and I unfollowed and if it's true it isn't following user second time. So my question is what program etc. do You recommend to do this intelligent script.
