Instagram problem

Hello guys! I have an account with 80k+ followers on Instagram. It was like I used to gain 600-1200 followers everyday. I didn’t changed anything in my content nor I used any third party application. In March suddenly it start losing followers instead of growing and its keep losing . I don’t know what the issue I checked everywhere I can’t find anything about this. I spent over one year in this account and it just stopped growing at all. It’s been 13 weeks now.
Can anyone explain what’s happening ?

Send me the handle for the account

I feel like Instagram is going hard deleting inactive and bot accounts l. I have a huge variation in gains and losses everyday (I own a 600k and 200k account)

But still like it’s been 13 weeks and I’m still losing followers. Ok let’s take it as Instagram is deleting followers but I used to gain 500-1000 followers each day now I’m gaining like 50-80 hardly
