How to block leechers in uTorrent

Updated April 17, 2017

Peer-to-peer file sharing systems such as BitTorrent rely on users distributing files as well as downloading them. If you suspect that another user is regularly leeching -- downloading files without also seeding and uploading files -- you can block him from connecting to you on the uTorrent BitTorrent client by adding his computer's Internet Protocol address to the application's IP Filter list. To block a suspected leecher's IP address, you'll need to edit the uTorrent IP Filter file in your computer's Notepad plain text editor program.

Click to highlight and select the name of the file that you suspect is being leeched in the uTorrent "Name" window in the centre of the screen.

Click the "Peers" tab in the status pane in the lower half of the screen. Copy or write down the IP address of each suspected leecher, for example, "123.456.78.9".

Launch the Notepad plain text editor program. Click "File" in the main menu, and then click "Open" to launch the folder and file browser window.

Go to "Computer" and then double-click the icon for your main hard disk drive, which is usually the "C:" drive. Go to "Users | [YourName] | AppData | uTorrent" in the folder and file browser window.

Double-click the "Ipfilter.dat" file to open the text file in Notepad. Paste or type the IP address for each leecher on to a new line in the document. Each IP address must be on a separate line in the document. Save the edited document and exit Notepad.

Click the "Settings" button with the gears icon in uTorrent's top menu bar. Select "Advanced" in the left menu, and then click to highlight the "ipfilter.enable" entry in the "Advanced Options" screen. Click to enable the "True" radio button, and then select "Apply" to implement the changes followed by "OK" to close the window.

Click the "Peers" tab in the status pane at the bottom of the main uTorrent screen. Right-click inside the pane, and then select "Reload IPFilter" from the context menu.


Sometimes firewall or network problems can prevent another user from uploading or seeding files on a BitTorrent client, so give people a chance to resolve these issues before blocking them on uTorrent.
