This is an expanded list for protection against spammers and other abusers of gnutella.
Place the list in this archive, called "hostiles.txt", into the folder C:\Program Files\BearShare\db.
The smaller copy already there will not be lost, as it is already built in to BearShare.

LimeWire users:
Place "hostiles.txt", into LimeWire's settings folder.

On Windows : C:\Documents and Settings\YOUR_NAME\.limewire
Alternate location: C:\Documents and Settings\YOUR_NAME\Application Data\Limewire
(You may have to change a setting in Explorer to be able to see this folder.
Go to the Tools menu, then Folder Options, switch to the View tab and turn on "Show hidden files and folders".)

On Windows Vista: C:\Users\your username\AppData\Roaming\LimeWire
LW Vista users - if you need help finding the LimeWire folder then please check this link for info: LimeWire Pref Folder in Vista

On Mac OSX 10.4 and up : Macintosh HD/Users/YOUR_NAME/Library/Preferences/LimeWire


Expect a significant delay as BearShare starts up.
Loading this list is the first thing it does, and apparently it has to convert it internally as it does so.
Update - Feb, 18 2005: BearShare 4.7.0.70 and up now load the list almost instantly. Thanks, Ed!

CPU usage will be higher if you are running an ultrapeer, but BearShare will stay in leaf mode unless you have a fast computer.
If you find it too heavy a load, go to Setup/Service and put a checkmark on "Never become an ultrapeer"
Update - Feb. 23, 2005: BearShare 4.7.0.71 and up now run the list more efficiently. Thanks again, Ed! ;]

Update - July 12, 2005:
A new bug in versions of BearShare (5.0 and up) makes older versions of the hostiles list
block many innocent IP addresses. DELETE AND STOP SHARING ALL HOSTILES LISTS OLDER THAN
JULY 12, 2005.

Update - July 16, 2005:
All LAN ranges are opened, so be careful about files from your own local network.

Added about 8800 hosts infected with the prolific VB:CC worm. The source list
for this worm will be rotated slowly enough for most of the blocked hosts to
detect and clean themselves before they drop from the list. Those few that
fail to remove it will roll forward to a longer term blocklist. The VB:CC list will
probably stabilize to slightly over 10,000 for the next few months and taper off
to near zero as people update their antivirus scanners.

Update - September 26, 2005:
More worms and trojans added. The list is now about as big as it will ever get,
with 223,916 rules, and I'd need more RAM to make it any bigger. ;]

Update - September 28, 2005:
Catching up with a notorious spammer who just happened to change tactics as
the list was updated on Monday. A coincidence, I'm sure…

Update - December 4, 2005:
Added many more worms and heavy spammers, with thousands of sites, but
constantly improving intel results in a slightly smaller and more effective list.

Update - February 1, 2007:
Notice the name change? That's right, it's not just for BearShare anymore.
LimeWire 4.13 and up can use this list now.

Update - February 11, 2007:
New Worm. It's still small, so get stomping! ;]

Update - March 3, 2007:
Skyrider (that new commercial P2P spammer announced last year) finally pops up on our RADAR! ;]

Update - July 22, 2007:
More info makes raw input top 800.000, but better intel shrinks the final result to less than half.

Update - January 12, 2008:
Continuing improvements in intel are still shrinking the list while covering more
address space, and most of the worms that were a major problem a year or more
ago are quickly going extinct. We're mostly fighting the last few desperate
spammers now, and recent updates to LimeWire are helping stomp them out of the
network.

PLEASE REMEMBER TO DELETE THE PREVIOUS LISTS!
They go stale and should be replaced often.

Here's a web link to the ZIP file:TechNutopia Fullsize Hostiles List (Original out-of-date old version, date: 2011-06-12)
…and another: TechNutopia Fullsize Hostiles List


Edit by LOTR, the above hostiles file has not been updated since mid 2011 or earlier, thus a new updated version below:

New Fullsize Hostiles list 2013

Download the Fullsize Hostiles List 2013 via 4Shared (need to be a 4Shared member to use their downloads) and the no Jap Block version via 4Shared.

via SaberCat (recommended)

Download the Fullsize Hostiles List 2013 via MediaFire - (If you wish to use an installer instead, find it either at MediaFire or SaberCat.)

Now option to choose a Hostiles file which does or does not block most of the Japanese clients. Edit February 2013: a single installer is now inclusive of both options and for either standard BearShare or the BearShare 5.1 Beta Test version. The blocklist is updated approximately every 2 months. Edit: March: fixed a silly error in the installer. I must have been experimenting, sleepy and forgot partial code still there as one choice would not install an appropriate file.
Filenames:
BearShare - Hostiles Blocklist 2013 installer (both)
Hostiles_2013-NoJapBlocks
Hostiles_2013

The hostiles files have been put together in same folder as other BearShare material to download from. For details see here or here for the Japanese block choice.

(If LimeWire users were to use this Netmask version of the hostiles, you should change the name from Hostiles to hostiles (all lower-case letters.) Otherwise the file is ignored.)

Windows 8 or later users will either need to use the installer or else, change the permissions of the BearShare program folder and reboot computer so you have permission to replace items in the program's db folder.
