Pipes is a free online service that lets you remix popular feed types and create data mashups using a visual editor. You can use Pipes to run your own web projects, or publish and share your own web services without ever having to write a line of code.

Defines <access:restriction relationship="allow" /> and deny to declare whether or not the feed can be re-published, made available to search etc.

I imagine there are many people syndicating "private" feeds through Bloglines and inadvertently making them public.
