Using mktorrent:

mktorrent -a http://torrent.tracker.net:9000/announce \
          -a udp://torrent.tracker.net:9000 \
          -n 'Torrent Name' \
          -o torrent_name.torrent \
          'Torrent Directory'

Note that any number of announce parameters (-a) are allowed and that they do not have to point to the same same domain.

Torrent clients such as qBittorrent allow blocking p2p peers based on a provided blacklist. Since the blacklist may be updated periodically, it must be re-downloaded on a schedule.

For Windows and using only native tools, the peer block list can be downloaded using the task scheduler and bitsadmin. The following Windows task can be saved to a file and them imported in "Task Scheduler":

The corresponding script file download-peerblock.bat is the following:

download-peerblock.bat

bitsadmin /create download-peerblock
bitsadmin /setnotifycmdline download-peerblock C:\Windows\System32\bitsadmin.exe "C:\Windows\System32\bitsadmin.exe /complete download-peerblock"
bitsadmin /addfile download-peerblock http://omeglewarden.weebly.com/uploads/6/9/2/6/6926744/anti-p2p-companies.p2p C:\Users\office\Documents\anti-p2p-companies.p2p
bitsadmin /resume download-peerblock

A file can be placed at /etc/cron.daily/peerblock with the following contents:

peerblock

#!/bin/sh
 
/usr/bin/wget -q -c -O /opt/peerblock/anti-p2p-companies.p2p http://omeglewarden.weebly.com/uploads/6/9/2/6/6926744/anti-p2p-companies.p2p

that will download the peer block file to the /opt/peerblock directory.
