After activating af_zz_imgproxy, I often have share links at the bottom at the article that cannot be fetched from feeds.feedburner.com. The result typically looks like this:
When all is good, the share links look as follows:
Besides the fact that the failed request images don’t look nice, I’m thinking that these share links are actually one more way for Google to track our every move, by providing unique image URLs for each displayed feed item.
So I was looking for a way to exclude them from the articles. I managed that by adding an exclusion in the af_fsckportal plugin on feeds.feedburner.com images.
Maybe it would be better to put that on a separate plugin, or maybe there would be a different approach within or outside of tt-rss.
I’d be glad to send a pull request for my modification of the af_fsckportal plugin, or to get feedback about other approaches.
