Block alexa from sniffing around

We all know alexa and their famous rank but there has been something else bugging me recently.

Alexa also records up- and downstream sites meaning they show to everybody which pages did the users visited before and after they have been visiting your site.

Here are the problems:
1. CPV networks are shown as upstream sites (not very good if the affiliate manager has a look at this)
2. Even the merchant's page are shown as upstream site, which is highly unlikely to be that way using white hat ( should only appear as downstream)

So, I have had a script developed to block all users using the alexa toolbar but they still send a request to my site (and getting 403).

Has anybody thought about that and has a solution or some thoughts on how to solve these problems?

lol alexa is not like that. Every computer has alexa spyware built in Microsoft Windows products lol. Alexa calculate all traffic from computers, so it knows exactly what's upstream sites and what's downstream sites.

You can't block Alexa from getting your stats, but you can signup webmasters in Alexa and ask them to filter your site.

OK, ask them to filter the website... that could work.

Just had a look at their site and they suggest to disallow them to crawl the site... question is if I disallow crawling, will they stop displaying up and downstream?

Anybody with any experience here if the completely erase the site from the alexa stats?
Anyways, will try that...

disallow alexa crawler & sign up webmasters section + request remove stats

That's what I got as a I made a request to have my alexa stats removed:

'the robots.txt file will remove your site from our search index (and the Internet Archive)'

'none of that will remove your site from our traffic listings. Our traffic stats come from our own data and we will not delete them'

you see, that's a bit confusing... they remove the site from their search but they don't delete the stats.
anyways, I added the robots text and will keep an eye on that.
After looking through their forum it seems like they only delete contact information.
