Commenting on Instagram Ads

Long-time lurker, first time poster here.

I can't seem to find any information to suggest it's possible to create farmed instagram accounts that can comment on instagram ads.

The goal: Create 50+ realistic instagram user accounts (no big accounts, each should look like a normal user that posts occasionally) that can custom comment on specific instagram advertisments.

I have FB ad ID's, but I don't think I can use these. There doesn't seem to be any type of tag/url/ID that I can plug into a program like instadub, etc, to 'summon an army' of custom commenting bots.

Besides purchasing several smartphones and manually swiping through feeds until ads appear, are their any cheaper ways to do this? I've looked at android emulators, etc, and haven't found anything usable.

I wish to know this too.
All you can do for now is to set the ad for retargeting and people that like your page, and then like the page and visit the website from that accounts so the ad will appear really soon.
