Yes, gnutella suffers from spam. And it does not always require a fair amount
of
bandwidth to spam the network. Many of the newer clients cache responses, so
send out a
number of replies, and then these get cached, and then automatically used later
on by
other peers. It is also somewhat difficult to stop this spam, because few
clients support
filtering of sources (maybe this has changed recently) and the fact that the
spam may have
actually come from the cache of a nice client.
And, there is actually spamming on napster, although to a much smaller scale.
Now here is a question. Is there any kind of feedback in this kind of
searching system?
Could someone upload a ton of meta data for spamming purposes? If you found a
meta data
key that contained spam (i.e. referenced some file that was a short audio clip
chastising
mp3 sharing) is there a way to remove or filter it? Would you even want such a
feature?
And finally, what are the limits to what one person can insert into the network
as far as
meta data is concerned? In Gnutella bandwidth is a limiting factor. If
someone spams
freenet can they persist this spam indefinately since it will appear popular
(i.e. using
very common and popular keys to ensure numerous matches) ?
Some things to ponder on. I suppose that this may not be too large of a
problem, but I
can see it becoming such very easily. Kind of like those spam kits they sell
now. Anyone
can be a spammer. What happens when such a kit is available for freenet?
Best regards,
Martin Peck.
