Organic Followers

So my account is gaining around 30 organic followers a day (10k plus account). By the end of the day, socialblade is showing a net gain of between 2-10 followers which seems like a lot of unfollows. I post high quality content that is very enjoyable to look at. What gives?

My other main question that I can't seem to figure out. Another account in my niche with a very close amount of total followers has follower gains of upwards of 100 per day! That's with no change in following numbers. What could be the reason for these differences in net follower gains? For background, I'm not running a bot and haven't since the Instagress days. Engagement rate is around 3.1 to 3.6 percent on posts.

Thanks for any advice.

Any ideas/advice?

did you check what kind of accounts unfollow you? banned accounts, bots or regular users? this could guide you to the answer.
many apps have the option to check who exactly unfollow you. i use tracker for iphone (not affiliate).

This is caused by using popular hashtags like #fashion #fitness etc. Bots are targeted on these hashtags and they will follow you, but also unfollow you in 1 or 2 days

I have 13.6k follower and account organic growth 70-90 follower/day

Are there any websites (like socialblade or similar) that are able to see this or do you have to login using Instagram API? Forgive me, I'm not super familiar with this but I heard it's not good to login to a bunch of third party apps with your account.
