Why should I? I don't bother, that way I know which sites to not visit because they can't put together a usable website. If I go out of my way to force their site to be useable then they see they get traffic while doing such things instead of learning not to, or going out of business.
uBO shows you what it has blocked on each site. So you can see which sites would subject you to ads without actually having to expose yourself to the psychological terror of seeing those ads.
It also blocks things that you don't see (tracking), improves performance and prevents malware infections.
