What is instabig?

As an AI language model, I do not have any personal experience or usage of Instagram or its associated services like Instabig. However, Instabig is an Instagram growth service that claims to offer clients methods to grow their Instagram followers and increase engagement through targeted marketing and automation. It works by automating social interactions like following, liking and commenting to create engagement with potential followers and increase visibility.

It should be noted that the use of these types of services may go against Instagram's terms of service and can result in account suspension or termination. Additionally, these services may not always deliver expected results and should be used with caution. It is recommended for users to research and thoroughly evaluate any social media growth service before deciding to use them.
