I assume that it would suffice, if users could just vote down by banning 
files. 
Excluding bad results is done quite routinely, and if tehre's a nice friendly 
Trash Button, I assume that most people will vote often, if only to get rid 
of spam results for themselves and normal use-patterns would result in a good 
voting base; maybe not of many good votes, but at least of many bad results, 
which would solve the spam-problem. 

And if people share files they want to support, they are likely to vote them 
up. 

As I remember from my useage of Credence, the main problem was finding other 
Credence users, and finding them again. 

But this shouldn't be a problem anymore, as soon as we can use teh DHT to 
locate unique hosts. 

As long as the network consists mainly of good hosts (which we have to assume 
when we want to have any chance; if tehre are more spammers than regular 
nodes, there won't be any possible protection, but in the current network, 
they'd need millions of _active_ spam-nodes for that), Credence should solve 
the spam-problem.

And to exclude the results in the count, so the leaf keeps DQ active until it 
has enough uncorrelated and high correlated results.

But a node can still send me spam - and the network loses te ability to 
protect itself (for example, every node could deny forwarding to low 
correlated results, which gives no advantage to spammers, because they can 
already do this, and it doesn't require a central blacklist (which is doomed 
to be outdated at all times), because it solely needs decentral voting). 

So sending results out-of-band can become a probem instead of an advantage. 
Or did already become a problem.
