Xunlei never upload even one byte to BitTorrent public network. Let's fuck it.

This script allow you to ban other peers basing on its client name. And you can customize your own regex to ban more clients.

bash script

PLEASE download latest version from github: https://github.com/recolic/daily-scripts/blob/one/mybin/ban-xunlei-d.sh

Just save this script on your machine, enable qBitTorrent WebUI, and run it with bash!

#!/bin/bash

# Configure your qBitTorrent API endpoint. 
#   Enable it in Tools->Web UI->Web User Interface. By default, it's 127.0.0.1:8080. 
#   Usually, you want to enable 'bypass authentication for clients on localhost'. If you still want to set a 
#     password, just add `-u username:password` option to the curl command. 
api_endpoint="http://127.0.0.1:8080/api/v2"
# You can customize the blacklist keywords. 
blacklists=(
    "Xunlei"
    "XL00"
    "^7\."

If you want to ban it temporarily instead of permanently, use curl_wrapped "$api_endpoint/app/setPreferences" --data "json={"banned_IPs":"$ipn"}"

Python script

@EchterAlsFake converted the bash script into a Python script and also compiled it to binary for Windows and Linux. You can find EchterAlsFake's project here: https://github.com/EchterAlsFake/qbittorrent_peer_ban
