-3.10. Why would anybody want to see a checkerboard pattern?
-
-This can be helpful for troubleshooting problems. It might also be good for
-anyone new to Privoxy so that they can see if their favorite pages are
-displaying correctly, and Privoxy is not inadvertently removing something
-important.

-3.11. I see large red banners on some pages that say "Blocked". Why and how do
-I get rid of this?
-
-These are URLs that match something in one of Privoxy's block actions ("+block"
-). It is meant to be a warning so that you know something has been blocked and
-an easy way for you to see why. These are handled differently than what has
-been defined explicitly as "images" (e.g. ads that are GIF image files).
-Depending on the URL itself, it is sometimes hard for Privoxy to really know
-whether there is indeed an ad image there or not. And there are limitations as
-to what Privoxy can do to "fool" the browser.
-
-For instance, if the ad is in a frame, then it is embedded in the separate HTML
-page used for the frame. In this case, you cannot just substitute an aribitrary
-image (like we would for a "blank" image), for an HTML page. The browser is
-expecting an HTML page, and that is what it must have for frames. Such
-situations can be a little trickier to deal with, and Privoxy may show the
-"Blocked" page, despite your best efforts.
-
-If you want these to be treated as if they were images, so that they can be
-made invisible, you can try moving the offending URL from the "+block" section
-to the "+imageblock" section of your actions file. Just be forewarned, if any
-URL is made "invisible", you may not have any inkling that something has been
-removed from that page, or why. If this approach does not work, then you are
-probably dealing with a frame (or "ilayer"), and the only thing that can go
-there is an HTML page of some sort.
-
-To deal with this situation, you could modify the "block" HTML template that is
-used by Privoxy to display this, and make it something more to your liking.
-Currently, there is no configuration option for this. You will have to modify,
-or create your own page, and use this to replace templates/blocked, which is
-what Privoxy uses to display the "Blocked" page.
-
-Another way to deal with this is find why and where Privoxy is blocking the
-frame, and diable this. Then let the "+set-image-blocker" action handle the ad
-that is embedded in the frame's HTML page.
