The clarification is much appreciated. My understanding is that BBR ring sig pruning linearly reduces blockchain bloat, but is not the holy grail of transaction pruning required for logarithmic bloat reduction of the kind found in XCN's mini-blockchain.
To be clear, ring sig pruning prevents a little bit of bloat, while transaction pruning removes substantial accumulated bloat.
Also, 'dust' is the atomic unit of 'bloat.'
Did I get that right? What do I win?

Spot on. Linear reductions are easy. Logarithmic are significantly harder. For your efforts you get a whale.
In CryptoNote coins ring signature is 60-90% of transaction size. With pruning ring signatures you get 60-90% smaller blockchain, compared with other cryptonote coins, you win only this here.
Yes, that is a correct example of linear. You get a whale too!
PS. In your next botnet / cryptocurrency / library project please do Star Wars references, they're a great deal more palatable than the Futurama references. And then that way you can say "I love you" and I can say "I know"

You angry and blind. You trying to insult me, just because you have nothing to say in substance.
I have my own reasons of being anonymous, and people who i work with know exactly why, and this have no relations with your fantasy about botnets.
Sorry for off-topic.
