Follow all users on a twitter page

Question

I'm on https://twitter.com/#!/username/followers ; is there any greasemonkey script to follow all the twitter users on that page?

Answer 1

Here's a new one which also employs a delay to prevent spam issues.

var FOLLOW_PAUSE = 1250;
var FOLLOW_RAND = 250; 
var PAGE_WAIT = 2000;
__cnt__ = 0; 
var f;
f = function() {
        var eles;
        var __lcnt__ = 0;
        eles = jQuery('.Grid-cell .not-following .follow-text').each(function(i, ele) {
                    ele = jQuery(ele);
                    if (ele.css('display') != 'block') {
                        console.trace('Already following: ' + i);
                        return;
                    }
                    setTimeout(function() {
                              console.trace("Following " + i + " of " + eles.length);
                            ele.click();
                            if ((eles.length - 1) == i) {
                                console.trace("Scrolling...");
                                window.scrollTo(0, document.body.scrollHeight);
                                setTimeout(function() {
                                    f();
                                }, PAGE_WAIT);
                            }
                    }, __lcnt__++ * FOLLOW_PAUSE + Math.random()*(FOLLOW_RAND) - FOLLOW_RAND/2);
                    __cnt__++;
        });
}
f();

What it does:

• Looks for follow buttons
• Checks that you aren't already following or pending (display: block check)
• Sets a timer to click the FOLLOW buttons every 500ms to prevent spam issues.
• NEW! When it's done them all, scrolls the page and waits a couple seconds for the next loads to appear, then repeats the whole process!

Notes for hackers:

• Works on Chrome latest version and Twitter as of the 30th of Sep 2016.
• You seem to need to "click" the DIV inside the A tag, not the A tag itself.
• HOMEWORK: Maybe try jQuery's live() function to auto-click any new buttons which show up after the initial page load :)

Disclaimer: This is not a hack...just a technique to save some wrist and finger RSI :) Regardless, use cautiously and respectfully.

UPDATE: Improved for latest twitter. Now employs randomness in the timing to make you look less like a bot
