Instagram Unfollower Finder

You can find who don't follow you back on instagram manually by searching. But it can be a very time consuming task to do. Here is a simple & very efficient way to do that. You can use this script to Find who hasn't followed you back in seconds.

Usage

1. Sign in to your Instagram account in any web browser.
2. Open browser's console / devtools by pressing F12 on your keyboard.
3. Type "allow pasting" on console & press enter.
4. Copy below script by clicking the clipboard icon on the right.
5. Paste and wait few seconds for process to finish.

class Script {
    constructor() {
        this.unfollowers = [];
        this.canQuery = true;
        this.nextPageHash = "";
        this.requestsCount = 0;
        this.followingCount = 0;
        this.currentPageCount = 0;
        this.estimatedStepValue = 0;
    }

    static sleep = t => new Promise(e => setTimeout(e, t));

    static printMessage = (t, e = "log") => {
        console[e](`%c${t}`, "padding: 0.5rem 0; font-size: 1rem; font-weight: 700;");
    };

    async handleOutput(t) {
        if (console.clear(), "PROGRESS" === t) {
            let e = `${this.currentPageCount}/${this.followingCount}`,
                s = Math.floor(this.currentPageCount / this.followingCount * 100),
                i = `Progress ${e} (${s}% - ETA: ${(() => {
                    let t = this.followingCount - this.currentPageCount,
                        e = Math.floor(t / this.estimatedStepValue);
                    return `${Math.floor((3 * e + 15 * Math.floor(e / 5)) / 60)} minute(s)`;
                })()})`;
            Script.printMessage(i, "warn");
        }
