Yeah, I’ve looked into that too. There are a few tools out there that claim to show who someone has recently followed or unfollowed on Instagram, but honestly, most of them aren’t super reliable. Some work for a bit, then stop updating properly or miss certain changes. I tried one called
recentfollow, it seemed to work decently at first, but it's still limited by Instagram’s privacy settings and restrictions. Plus, there’s always that question of how safe it is to log in or share account info.
