+There are many lists out there which purpose is to enhance privacy protection. Many missing entries though. So here:
+
+##### Twitter widget
+
+I don't know why this one is not blocked by Fanboy Annoyance, as the list already block many other twitter widget-related stuff. So if you use above list, you may want to add the following to your filters:
+
+`||platform.twitter.com/widgets.js$third-party`
+
+##### Gravatar
+
+Each time you visit a site which pull cute little avatar image aside (typically) a commenter's name, there is a corresponding request to [Gravatar](https://gravatar.com)'s web site, and the HTTP `referer` header contains the site you are visiting. The tracking potential is too much for me, so I block all these requests:
+
+`||gravatar.com^$third-party`
+
+I don't know if, and how much this breaks things. But for now I am happy to not have my browsing habits disclosed to gravatar.com. I can live without these cute thumbnails.
