Exlain more about DoS and spam prevention in documentation

Hi,

What does ZeroNet do to prevent bad peer actors, for example, a (modified) peer which only holds connection open and never sends any data thus increasing time for others who asked it for data which it doesnt send. Does zeronet have any mechanism to avoid such a peer in the future? What if I would join zeronet with 100s (meh even 1000) of such peers, the network would slow down to a halt. Or even worse, a peer which sends the pieces very slowly at 1-4kb/s range.

On the other side of the coin, what would prevent 1000s of (modified) peers all to request same site from the owner, but never share any pieces with the rest of the swarm? That would effectively suck the bandwidth of the site owner for no purpose other than to prevent others from getting the zite. How is a peer identified, is it local only to the zite/peer, or is there a public/global system of accounting of bad peers?

Does Zeronet prevent such attacks? Does zeronet keep any accounting on ratio of peers in the bittorrent swarm? If not is there plans to do that.
