Instagram Keeps Making Me Follow Random People Automatically

I’m reaching out because I’ve encountered a rather unusual and worrying problem with my Instagram account. Over the last couple of days, I've noticed unfamiliar accounts popping up in my following list. I unfollow them, assuming it’s just a temporary issue, but a few hours later, they’re back on my list—without any action on my part. I feel like I'm losing control of my account, and it's becoming quite concerning. I’ve reviewed all security settings, updated my password, and logged out of all devices, yet the problem persists. I’m not only frustrated—I feel unsettled realizing my account appears to be functioning independently. I truly hope this issue is resolved promptly, as my comfort with using the app has diminished significantly.
