Open Redirects Under Attack by Spammers

Albino alligator

I wrote a post last Friday on the Google Webmaster Central Blog about the widespread abuse of open redirects round the web.  If you have some code on your site that will redirect users to an arbitrary destination based on url parameters, watch out.

“But Jason,” you say, “why would I have code that would redirect users to an arbitrary destination based on url parameters?”  You might be surprised.  Code that tracks clicks for ads or analytics, search results pages, and even some login pages are vulnerable.

There are actually lots of legitimate reasons to redirect users, but unfortunately spammers can use them too if you’re not careful.  Read the post to find out more and learn ways to make your site less attractive to attackers.

Okay, we should dump the Electoral College – but no need to spam my blog!

One of the things I mentioned in my last post was how the Electoral College distorts the vote in favor of those in small-population states.

I got a comment from NationalPopularVote.com along these lines…

The major shortcoming of the current system of electing the President is that presidential candidates concentrate their attention on a handful of closely divided “battleground” states. In 2004 two-thirds of the visits and money were focused in just six states; 88% on 9 states, and 99% of the money went to just 16 states. Two-thirds of the states and people were merely spectators to the presidential election. Candidates have no reason to poll, visit, advertise, organize, campaign, or worry about the voter concerns in states where they are safely ahead or hopelessly behind. The reason for this is the winner-take-all rule under which all of a state’s electoral votes are awarded to the candidate who gets the most votes in each separate state.

They make a good argument, and I agree with them, but I find it pretty reprehensible that they are spamming blogs to make their point.  If the comment is on-topic, why do I call it spamming?  Grab a snippet of text and do an exact-phrase Google search by wrapping quotes around it, like this:

http://www.google.com/search?q=%22of+the+states+and+people+were+merely+spectators+to+the+presidential%22

As of this writing there are 233 occurrences of the exact same comment slathered all over the web.  It looks like they’re using an automated program to watch Technorati or Google Blog Search for posts about the Electoral College and autopost the same comment.  I’m going to email them and ask that they stop.

The phrase search is a good technique for discovering compliment spam as well.

In any event, we already looked at the fact that some people’s votes count four times as much because they live in a state with a small population.  Do the NationalPopularVote.com folks have a point about swing states?

One way to look at the power of your vote is to figure out the likelihood that yours will decide the election.  By this definition, it helps a little to be in a small-population state but the most important factor is how close the election is in your state – your best bet is to live in a swing state.  Andrew Gelman has a great article explaining why, but it’s pretty intuitive.  If you live in a safe Democrat state, for example, it doesn’t matter if you live in California or Rhode Island – your vote is much less likely to be the one to flip the state to one side or the other.  The same is true for safe Republican states, from Texas to Wyoming.

Comment Spam Article on the Google Webmaster Central Blog

I hate comment spam. I think it’s safe to say we all do. So how do you keep it off your blog or forum? Check out this article I wrote on the Google Webmaster Central Blog with some ways to prevent comment spam.

It’s interesting that one of the commenters brings up compliment spam – I just wrote about it on this blog a little while ago.

This was pretty cool for me, because I can’t really share much about my work at Google. It’s also fun to see my text translated into German.

Next up I’ll post an update on the baby name poll with more fun charts and graphs.
