-Rubbish data or garbage data, is a term used to describe, in the BitTorrent scene, downloaded [[http://wiki.bitcomet.com/doku.php?id=peers_seeds_torrent_tracker_dht_peer_exchange_pex_magnet_links#torrent|pieces]] which failed to pass the hash-check and consequently are discarded. They are regarded as garbage since they are of no use to the downloading client and only waste bandwidth and time.+Rubbish data or garbage data, is a term used to describe, in the BitTorrent scene, downloaded [[peers_seeds_torrent_tracker_dht_peer_exchange_pex_magnet_links#torrent|pieces]] which failed to pass the hash-check and consequently are discarded.

 **Possible causes** **Possible causes**
-  - Rubbish data is basically caused by peers sending bad packets to the swarm. Whether intentionally or unintentionally, that can't be easily determined. It could either be caused by peers having bad connections, as well as a variety of other things or by anti-piracy organizations which mingle into the torrent swarms using modified clients and release bad data intentionally, so as to hinder torrent users (in case you're downloading copy-righted material).+  - Rubbish data is basically caused by peers sending bad packets to the swarm. Whether intentionally or unintentionally, that can't be easily determined. It could either be caused by peers having bad connections, by a bad/unreliable/congested segment of network in the path between the other peer and you, as well as a variety of other things or by anti-piracy organizations which mingle into the torrent swarms using modified clients and release bad data intentionally, so as to hinder torrent users (in case you're downloading copy-righted material).
   - Another more prosaic reason for occurrences of garbage data might be your router. Certain routers are known to have a particular firmware implementation which may lead to corrupt data, especially on BitTorrent downloads (which by definition use a huge number of simultaneous connections). A good indicator for this, is getting garbage data for all or most of your torrents.    - Another more prosaic reason for occurrences of garbage data might be your router.

-  - The only solution, so far, to this problem is to download Peer Guardian: http://phoenixlabs.org.\\ Download and install the client, and when it comes to the screen of 'Updates' click on the check-boxes: Government, P2P, Ads. Then let PeerGuardian update its lists. Allow PeerGuardian to run every time your BitComet client is functioning. This may reduce, in some cases, the amount of garbage data you get, by refusing connections to some IPs known to interfere with P2P downloading.\\ **A reminder to users**: This program does not guarantee that you will receive nil rubbish data, or that you'll be "protected" from governmental agencies trying to obtain your IP address. A lot of users are under the general false idea that some programs are able to block all rubbish data or conceal them on the P2P networks; we can assure you that this is not true. The most that it can do is limit the amount of rubbish data being passed through to your torrent client.\\ However, whenever you use Peerguardian or Protowall alongside any P2P applications, be aware that if you configure it improperly, it may limit your download capability, especially for torrents that have peers in some of the ranges you might have chosen to block (such as educational institutions - university campuses).+  - The only solution, so far, to this problem is to download an IP-blocking program (such as Peer Guardian: http://phoenixlabs.org).\\ Download and install the client, and when it comes to the screen of 'Updates' click on the check-boxes: Government, P2P, Ads.

You can instead activate the Bluetack lists which are provided with PeerGuardian as an alternative to the default lists of PeerGuardian. PG should update from them, its IP lists automatically.\\ Or as a more versatile workaround or alternative solution you can go to the [[http://www.bluetack.co.uk/|Bluetack site]] and download their [[http://blocklistpro.com/download-center/view-details/blocklist-manager/1437-blocklist_manager_install_2.7.7.exe.html|Blocklist Manager]] application which is a very versatile an complete solution for automatically downloading and combining their multiple lists which are frequently updated. Also a list of recommended IP-blocking applications (PeerGuardian included) you may find on their page: [[http://blocklistpro.com/faqs/best-p2p-ip-filtering-programs-list.html|Best P2P IP Filtering Programs List]]. Any of those applications can use the up-to-date lists exported by Blocklist Manager, which offers the choice of converting/exporting its downloaded IP list array into over 20 different formats, so that it can fit most IP-blocking programs' formats, out there.  \\ <html><span style=color:darkred;font-weight:bold>ATTENTION!</span></html> //We DO NOT provide support for installing, configuring and using Blocklist Manager or any of the IP-blocking programs, so please, do not ask questions related to that into the BitComet forums. The [[http://blocklistpro.com/|BlocklistPro]] site provides, along with the application, extensive info covering the program's features and usage and their forum provides detailed guides, regarding the fine-grained configuration of the application. Therefore, please use those resources for clearing any questions you may have, regarding Blocklist Manager.//
   - In order to verify if your router is the cause of your trouble, you should try and take the router out of the loop, if possible, or if the modem and router are integrated try to replace it for testing purpose. Then run your BitTorrent client for a while and check if you get the same average amount of garbage data (some rubbish data may still come for reasons described in paragraph 1).\\ Also you might try updating your router's firmware in order to see if that helps you get rid of the problem. If that doesn't cut it, you might consider changing your router.    - In order to verify if your router is the cause of your trouble, you should try and take the router out of the loop, if possible, or if the modem and router are integrated try to replace it for testing purpose.
