I remember many years back that I checked a site which had sent a client an email soliciting advertisers and touting its Alexa popularity.
The Alexa toolbar, though, had left a trail. Alexa indicated that visitors to the site which offered the ads also frequently visited a site that offered tips on how to manipulate your Alexa ranking. ;)
