Uncovering Digg Spam Networks


I’m starting to feel a bit sorry for Digg as they have to deal with a different type of spam problem to say email platforms, forums and blogs. However, I really feel that they could do a better job.

Take for instance this little blogging network I’ve just uncovered. A recent Digg made the Digg homepage outing indiafmcom as a spammer as within minutes of registering on Christmas day, he’d submitted hundreds of diggs, sometimes 3 or 4 a minute, which I didn’t even think was possible. Thanks to this post Digg closed the account.

I thought it’s be interesting to see if he was part of digg spam network, as all of his diggs seemed to be getting roughly the same amount of diggs. Not surprisingly, he was indeed getting help. However, these accounts haven’t been banned yet. Check out the articles recently dugg by these users, and how many of them are from indiadfmcom and how fast they were being dugg:

What these accounts seem to have also done, is prior to digging indiafmcom’s digg spam, is very quickly digg a couple dozen posts on the digg homepage, I think to try and trick digg’s rating system into thinking they are genuine diggers. This is only a small network of 6 people. Imagine the impact a network of 20-30 accounts could have. Digg hasn’t shut these accounts down yet, which makes me think they only caught indiafmcom because a user posted his details.

I can understand the difficulties in creating rules so that if a user diggs too many articles submitted by another user, as many diggers just digg the articles of the top 100 diggers. However, Digg really needs to implement standard spam rules that other services use like:

  • Not accepting too many submissions per minute/hour from one account etc
  • If a user diggs xx number of articles in a minute, then adding some kind of protection to make sure it’s a real person
  • Not allowing users to Digg or post articles for x days after registering. Drastic, but many forums do this and it has become an acceptable practice
  • If a user diggs more than XX% of their total diggs from one site, then don’t accept any more diggs until investigated
  • Not allowing users to digg articles until they’ve got an article on the homepage. Drastic I know (Digg kind of do this anyway, through the power given to its top users)

The sad thing about this, is that Indiafm.com is actually a very nice site with a PR of 7. I wonder if the actions of this one user who may or may not be associated with indiafm (in fact he could be deliberately be trying to get indiafm banned), will result in indiafm.com being banned from Digg? I haven’t tried submitting a indiafm url to digg as I don’t want my account to be potentially banned!

    That’s the main problem of those user driven sites such as Digg. Sadly, people take it so seriously, anybody could get anybody’s account banned.

    Human beings are aways exceptionally resourcefull.
    People getting around rules is always a fact of life.
    Cat and mouse.
    It is a question of keeping it within reasonable limits and focusing on the core product rather than placing one’s efforts soley on stomping it out.

    I don’t think an hourly limit will be enforced. I remember reading somewhere that since earns advertising revenue via the pageviews, more of them are better.
    An hourly limit will restrict the content.

    Okay man, thats just not cool. I have no idea why my name and profile are linked in this post, but I assure you i am not part of any spam network. I would really appreciate it if you removed my name and profile from here… thanks

    EvilGold or ‘Joe’ - why then was you along with the other people listed digging so many posts from indiadfmcom, at such an unbelievable rate?

    Are you seriously going to say that you read every single one and thought they were worth a Digg? You must do well at school being able to absorb so much info so fast!

    I do believe you are mistaken. I havnt dugg any stories on indiafm, in fact I dugg a bunch of them down.

    Ah! i see… you cant tell if the stories where dugg up or down by me, only i can see that when im logged in… So you assumed that i dugg them up. Well anyway, I hope you can look at my profile and notice the other 1,000 or so non spam stories and please remove me from your blog entry.

    There was a front page story here: http://digg.com/tech_news/Worst_DIGG_user_ever (which the actual post doesnt work anymore) pointing out that the user indiafmcom submitted 100’s of stories. I decided to digg as many of them down as i could before i got bored. I got threw a dozen or so.
