As a user with a decent amount of followers(almost 28k), all of these accounts make me angry. I spend so much time filming and editing posts only for some T-shirt woodworking account to steal it and gain more followers than me. I don't care what size the account is that is sharing it. I report them and block them. These accounts are stealing content and making money from stolen content. It makes me sick seeing these accounts have #ad in posts because I know they didn't work hard to get where they are.
I would expect that reporting them doesn't do all that much, since Instagram doesn't really have an incentive to make that right for you (unless, of course, you're a large content creator with a ton of followers; in that case, I'm sure Instagram does want to keep you happy).
Instead, file a DMCA takedown notice with Instagram referencing the stolen work. They're required by law to comply and take it down. I expect that most content thieves won't see it as worth it to contest the takedown and open themselves up to legal liability.
Not true at all, I've reported MANY of my unauthorized posts and all have been swiftly dealt with by Instagram. In my experience, they take it seriously when you provide proof of your post, and theirs.
