@Unihedro Go to a nonmetanonwiki question with many answers, like
this. Paste this script (first time I showed an invalid script,trynow) in the address bar and click enter: javascript:var down = document.getElementsByClassName("vote-down-off");for(var a=0;a<down.length;a++){down[a].click()};var i = 0;var timer = setInterval(function(){if(i<down.length){down[i].click();i++;}else{timer=null;}},200).
