Note: Working for every type of account.
Steps:
Go to your Instagram
Go to Search Bar and search any Hashtag related to your niche like mine is mobile photography
After you select the hashtag like #mobilephotography, open it.
Go to Recent Posts of selected Hashtag (#mobilephotography) and like all recent posts up to 60 posts.
That’s All.
Remember always use the correct hashtag related to your niche and don’t like too many posts only 60-80 likes per hour otherwise you would get a temporary ban from liking any posts.
And if you got a temporary ban limit notification then suddenly clear storage and cache from the Instagram app, also uninstall the app and after some time reinstall the app."
