I could say OGads approves most of the accounts. They're a friendly network and definitely understand when someone is just starting out. You can mention you'll be using Instagram to promote and you should be accepted.
I just mentioned using OGads' premade landing pages. - http://members.ogads.com/landingpagerequest.php
You see, the amount you make directly depends on the number of accounts you have running. For starters, run 25-30 accounts well and once you know your way around Instagram, scale up.
I don't post photos no matter what niche I'm trying. Photo increase ban rates regardless and I like to avoid that.
I only put shortened links in my bio. I'm constantly testing new things and need the analytics of link clicks.

I do put them instantly on aged accounts. I haven't used fresh accounts for a while now.
I'm not building LPs, I'm simply using OGads LPs. I rip them and host them myself is all.
1 Account per domain is safest.
There's an abundance of niches waiting for you here - http://members.ogads.com/landingpagerequest.php
The IP gets flagged really bad if multiple accounts get banned on it. I wouldn't recommend running more than 2 accounts on the same proxy.
All my lockers are set to CPI Prioritized.
Run 25-30 accounts well and once you're familiar with IG,scale up!

1 Account per proxy is the safest in my opinion.
I can't tell you what kind of people I follow. All I can say is, I put in usernames of large accounts on Massplanner and make it follow their followers. I haven't used gramdominator. It is an Instagram bot so I suppose you could. It's just basic follow/unfollow.
That's weird. Try canceling and re-requesting. Contact your Affiliate Manager if the problem persists.
Hahah you're being paranoid, yeah.

Instagram is definitely worth getting into.
I use Semi-dedicated proxies and put 1 Account per proxy.
Mate, it was saturated when I got into it and that was 7 months ago. Don't forget the fact that millions of new users join Instagram every day so it can never truly get saturated. Imagine if I stopped promoting CPA through Instagram just because I thought it was saturated, I wouldn't have made anything.
