a use for spam - verifying availability (e.g. for torrent)

so I can prove how available (and how much bandwidth i have, modulo asymmetry) by how much spam I get - i dont have to see the spam, but I can prove that i got it (e.g. summary hashes) and then use this to verify I am a high avaialbility, high capacity site -i could bootstrap my trust in (say) bittorrent from this...

how about this?

would there be a perverse incentive for people to spam themselves to get more bittorrent tokens? no - they would do better to just actually use the acpacity fore bittorrent

would spammers have an incentive to boost artificially, some sites over others? not really (as far as i can see) - a "popular" person would stay (at least pro rate) popular...
