Scroll to end and then Like all (Gab.ai bookmarklet)

// Go to http://mrcoles.com/bookmarklet/ and put the below script, LESS this comment, into the box. Don't check the option to include jQuery. The site will then give you a button ("this link") you can drag into your browser's UI and use anytime. Note that this is sluggish on profiles with a lot of posts because, obviously, it loads them all. Also note that if the script is activated on a hashtag page or something like that, it will still work, but obviously just keep loading posts ad infinitum and your computer will probably turn into syrup before it gets to the end to start the Like spamming.

    if (lastHit == 0 || (new Date().getTime() / 1000) - lastHit < 10)

        var nodes = document.evaluate('.//a[@class="post post--load"]//span[contains(text(),"Load more")]', document, null, XPathResult.ORDERED_NODE_SNAPSHOT_TYPE, null);

        if (nodes.snapshotLength > 0)
