Hi,

gnutella and g2 seem to be mostly useless these days, at least when using
mldonkey. I get (practically) no relevant hits, just the same dose of
auto-generated spam. Somehow this doesn't seem to happen when using
Shareaza.

For example, searching for "asdfgadcv" yields 72 results, e.g. "*Unique*
asdfgadcv Promo (XXX).rar", "01 asdfgadcv (256kbps) (2).zip" and so on.

I believe it would be possible to automatically filter these, at least until
the spammers come up with more sophisticated tools. If you search for a
random string say every hour and add the hashes of resulting hits to a filter
list, then the same spam hits needn't show up as hits when the user does a
real search.

I'm not sure how feasible it would be to automatically block the IPs of the
spammers; some of these files are pretty widespread (60+ sources reported on
G2, but on ed2k I have seen upwards of several thousand).

Even if automatic filtering is not implemented, the option to manually ignore
some search results in all future searches would be welcome.

Also, there seems to be an anomaly in search handling where search results
from previous searches creep into the list of results for a later search.
This only seems to affect Gnutella and G2. So, you search for foo, then
several hours later search for bar, and you get a result for "foo" in the
"bar" listing.

Additionally, the list of bootstrap/discovery services shipped with mldonkey
is so outdated that none of the URLs work. For this reason, a new mldonkey
installation can't connect to Gnutella at all. Shareaza seems to have an up
to date list, maybe you could borrow that?
