Hide bikes you don't want to see on OLX.ro, because it lacks -keyword filtering
< Feedback on OLX.ro Filter out crap bikes
Good to have! The reason I chose to fade out instead of hide is because sometimes the filters are wrong, since user-chosen titles can be so wacky.
Works also on other OLX websites.
A snippet to completely hide unwanted ads:
var opacity_or_hide = 2;
if (opacity_or_hide == 1) style.appendChild(document.createTextNode('.crap { opacity: 0.1 !important; }'));
if (opacity_or_hide == 2) style.appendChild(document.createTextNode('.crap { display: none !important; }'));
