It is happening again - this time worse. Amazon/Alexa is trying to shut down Statsaholic (formerly Alexaholic) by blocking the Alexa graphs. Statsaholic is a multiple site traffic comparison service that became popular lately for Seth Godin’s web 2.0 picks.

Statsholic responds in this way:

David vs. Goliath - On March 18, in response to legal action taken against me by Alexa over the use of their name in my domain alexaholic.com, I changed the name of this website to Statsaholic. Now, on March 23, Amazon/Alexa is still trying to shut this website down, this time by blocking their traffic graphs if you’re viewing them from this site (even though thousands of other websites, and Alexa’s own free widgets, serve their traffic graphs in exactly the same manner). I’m doing my best to keep the site up with some creative coding, but it’s not looking good for the little guy here. If you see a white box where the graph should be, that’s Alexa blocking us again. It appears that the decision makers at Amazon think mashups and creative use of their api is fine, unless you get successful with it.

The last point seems very true. Statsholic had started the comprehensive trafic comparison features much before Alexa itself (using Alexa’s own data). But it seems like Amazon’s API’s are not as open as they advertise it to be.

RIght now no clarification is available from Alexa / Amazon regarding this issue.

Update: It seems like Statsaholic wants to switch to other traffic data providers. Compete.com and Quantcast.com have already shown interest in providing their data.
