No silver bullet but a start. Hides some of the lowiq spammer posts of late- notice the post innertext contains only toLowerCase alphas. Downside is there's potential for false positive filtering of anons. Simple solution is post with atleast one toUpperCase character. Place in either devtools console or use the kun's userjs settings option.
function hidePost(post) { var $ele = $(post); // 2 lines taken from 8kun's main.js $ele.hide(); $ele.nextUntil(':not(br)').hide();}function spamSelector(post) { var body = post.querySelector('.body').innerText; // NOTE: continually modify as spam changes if (body.length 700 && !body.match(/[A-Z]/)) { return post; }}function hideSpam() { var posts = Array.from(document.querySelectorAll('.post')); var spam = posts.filter(spamSelector); spam.forEach(hidePost);}hideSpam();setInterval(hideSpam, 1000 * 15);
