  Finally another article that looked at the possible incentives that could be incorporated into the Bit Torrent community. This particular article focuses on a couple of the different incentive mechanisms that are on offer. Firstly the choking/unchoking method, but also a proposed mechanism where instead of the lottery like system employed with choking it's a more even spread of peer uploading, and the amount uploaded is based on the amount that a peer is willing to risk to possibly "establish cooperation" There is always the possibility that others may take advantage of a particular peer who may upload more generously than others but this way cooperation and the overall community could be strengthened as a peer may benefit if they go through a repeated exchange period and cooperate.
  
  Through the proposed mechanism in the article links between peers could be more easily forged, which is less possible in the choking system where a connection is dropped as soon as a better one is found. Free riders also receive benefits in this system. The article carries out a study to see which of the mechanisms proves more effective, and while the original choking mechanism proves to be more effective it is still susceptible to the free riders that have plagued it beforehand. As I have seen throughout the vast majority of articles that I have read, free riders are still heavily impacting the longevity and overall effectiveness of the Bit Torrent community and collaboration system.

  This paper has a unique story but similar in approach to many discussing Social Media, in that there are many papers that like to entertain the idea that people naturally don't want to share. Personally I struggle with these types of starting assumptions as it is foreign to me to not want to share and assist others and I think this also applies to participants collaborating over the internet using Social Media. Not all participants will want to share but the majority does or there are enough single entries that amount to a critical mass of participation to enable the medium to be a social success. The Prisoners Dilemma in this paper is a topic that can provide entertaining conversation. But I conclude that if you don't want to share at a point in time then ok with me because I will find others that do want to share. The transaction cost of the internet is so low that I do not have to force myself to interact with no sharers.
  
  I guess what I feel is the same as Mike Kent proposes in his paper Strangers in the Swarm. "the presence of freeloaders will make the swarm less efficient thus encouraging people to move to more efficient groups."
  
  I have experience two examples where I want to shop online a pay for something but because I could not find them in a shop or online I then turned to Bit Torrent to download them.
  
  1st. I wanted to buy the student version of Adobe Master Edition at the start of 2011. I walked the streets of Perth and got shops to call their other shops but no one had a copy I could buy. I then searched online but could not find any online store that would allow an Australian based buyer to purchase it. So I found an inexpensive solution just in time for my Digital Design classes started.
  
  Then at the start of this year I did another search to see if I could buy a student version of Master Edition online and I found could. I had to send my ID to prove I am a student along with $500 and I happily paid for the latest release of what I already had that did all I wanted it to do that was already a version ahead of what Curtin Uni uses.
  
  2nd I want to buy a copy of 7UP. This is the show about following folk from the UK and interviewing them every 7 years of their life. The only place I found that was in a torrent that took about 7 days to download. If I could find a copy I could pay for today then I would.
  
  So is there excellent sales opportunity information to be gained from evaluating Bit Torrents. As must as only 0.3% of traffic is legitimate I would be guessing that those heavily using it are under age or under paid. Bit Torrents enable future buyers to practice their commercial skills.

  As most of my readings are focusing on analyzing the operating status of BitTorrent world, in this task, I found more readings are relevant to the issue of free-riding. This paper again take notes on incentives in BitTorrent induce free-riding. Authors believe that the lack of reward and punishment can induce free riding to such a degree that the systems become inefficient.
  
  The interesting thing is, author illustrate the prisoner's dilemma with free riders. When they try to download, they need to face with the conflict between eagerness to download and the unwilling to upload. This implicate not everybody would like to share themselves however they like to get from others. Therefore, an incentive mechanism is developed for free riders.
  
  Of course, it makes me think about if free riding does become widespread, the engineer and scientist will work out the means to prevent it. However, this would probably lead to a negative direction that have unintended consequences, such as a loss of privacy, or user management.
  
  Overall, Free riding is a major issue for filesharing programs, and can greatly degrade their performance. It is a vulnerability that those who wish to make filesharing networks less popular can exploit. BitTorrent has been remarkably resilient to this so far.
