Flickr: block "group invite" comments for a given FlickrID.
This requires that you know your userid (not username, see the default entry below). You can discover your username here:
If you have an API key and want to grab the comments feed with group invites blocked from a username, try: http://pipes.yahoo.com/pipes/pipe.info?_id=zowFDFE83BGENfH0EpPZnA which calls another pipe of interest, the one that converts the username to a userid and grabs the complete comments feed.
