BINGO! Your in the dog house!
Basically it all comes down to keeping your settings human like.
DISCLAIMER: Some believe that as soon as you use MP, your are no longer viewed as human. Others believe that you are viewed as a human with conservative settings + some strategic filters.
I personally believe that my accounts are viewed as human like, as I am conservative with my settings. I have had no problems with these settings, and my accounts are growing at fantastic speeds with high engagement.
I completely disagree (please take no offence).
Here is why:
Instagram was designed based on the sole purpose to get exposure and grow by interacting with others (liking & commenting), and posting your pictures using hashtags. Instagram was NOT designed to follow thousands of people every day, and un-follow them to grow. In a sense consider growing your account by posting pictures as a White Hat Method, while Following/Un-Following is a Grey/Black Hat Method. The White Hat Method raises ZERO red flags, while following to many users will raise many red flags. If your looking for long term account stability then White Hat is the way to go.
You are limited to how many users you can follow every day. Lets say the maximum follow amount is 1,000/day. This means the maximum reach your account will have is 1,000. Not to mention you are forcefully trying to get followers this way. When you post pictures and get featured your reach is WAY BEYOND a 1,000 reach. Un-Popular hashtags get thousands of views every day. Times this by 30 hashtags, and you have a minimum reach of 30,000. Now imagine using popular hashtags! Your one picture would be seen by MILLIONS. In addition you are not forcefully trying to get followers. They are choosing to follow you since they are genuinely interested in your account.
Furthermore, when you follow (and expect a follow back) the person following you will feel like you owe them something. You followed them, and they followed you. Things are even. Now you want them to engage, so you need to engage with them in order for them to return the favor. They will like your pictures, and if they see that you are no longer engaging with their content they will un-follow. Worse they may continue to follow you but do not like or comment on your posts destroying your engagement rate one user at a time. When you get followers from posting a picture, they followed you because they like your content. These followers are more than happy to just receive daily posts from your account, and are less likely to expect anything else in return. That being said if you do like their pictures, they will enjoy it more since they do not expect it, and therefor are more likely to feel happy and engage more often with your posts.
The amount of followers you get from following/unfollowing is so tiny compared to the amount of followers you will get from posting pictures with the right hashtag strategy.
