Filtering ads in RSS feeds?

[eclipse]

Quote:I loaded both feeds with Firefox. I didn't see any ads

Beware of the preview mode, as every feed I tried in firefox and opera DIDN'T display any ads (although they WERE there). You could try also in IE, and FeedBurner will kick in and display a preview of their own (something to do with making the subscription more user friendly I guess?). This code apparently is embedded in the source feed.

Please take a look at the attached pics. Different interpretations of the standard? Why would the unfiltered ads display in "subscribed mode" but not in "preview mode"?

What about this...
This is part of the source from the preview in opera:

Code:

<p><a href="http://feedads.googleadservices.com/~at/3l_uhy3mKKW_q5qbxEm2bE8WEP8/a"><img src="http://feedads.googleadservices.com/~at/3l_uhy3mKKW_q5qbxEm2bE8WEP8/i" border="0" ismap="true"></img></a></p>

Once you are subscribed you can see the source of the feed as an attachment (mime encoded): (exact same extract)

Code:

<p><a href="http://feedads.googleadservices.com/~at/3l_uhy3mKKW_q5qbxEm2bE8WEP8/a"><img src="http://feedads.googleadservices.com/~at/3l_uhy3mKKW_q5qbxEm2bE8WEP8/i" border="0" ismap="true"></img></a></p>

Quote:Implementing feed filtering reliably would require a lot of examples! Dozens!

Up until now, only encountered ads in feeds in some way related to FeedBurner (and always google ads).
An easy way to tell if you're going to have ads is just entering the feed url address in IE. If you get a FeedBurner "friendly" page, you'll probably have ads from google (later in a reader, not in the preview)
