I don't know of any DiSo systems that use flooding and I don't know why they would. When you send something to your friends, it should go directly from your server to each of your friends' servers with no intermediaries involved. The only way something would go from you to Alice to Charlie is if Alice manually copied and pasted it, which she can do in any system (even a centralized one).

Well, all these communications systems (usenet, email, facebook) sort of do both 'flooding' for _public_ posts, as well as 'less than flooding' with posts that are made directed at a subset of the public. Of course all of this depends on being able to run/host servers against an internet connection that respects the 'Right To Serve'[1]. But there I go with my own social network flooding techniques... :)
