Hi

We all get spam, but this one annoyed me.

A while ago I was browsing for something online on Google. Followed a link to a site, which had a few things I was interested in and would have gone back that night to buy. At work so wasn't buying anything at that moment.

Left the site and 2 mins later I had an email from the site, with the items I had looked at.

I hadn't typed anything in on the site, certainly not my email address or the like and had never been to that site before.

All I can think of is that they managed to link to records of my email gained through cross site collection of details / cookies. Something like the way Google Analytics works (or maybe actual Google Analytics sourced data).

But a bit of a pig. Pity anyone who goes trying to buy a secret present for someone and lands up with a page sent with the details to that person!

Anyway, seems the spam is generated via these gits:-

All the best

Katy

Hi

Yes it is gmail, hence one (extra) reason it could be coming via Google Analytics data.

All the best

Are you Do-Not-Tracking? Just out of interest, not that I think it matters.

It's action tracking and cookies, you can place a tracking code on a website and set your email marketing campaign to trigger when certain actions are taken on the website.

I.e., user clicks in to "Electronics" category via a link. This link is being tracked via the email marketing software and automatically adds you in to some automation chain, i.e. "General Electronics" which is a series of emails designed to show you related products as well as the one you looked at.

Personally think it's a bit unethical to do this, if you didn't enter an email address to sign up for marketing, they shouldn't be allowed to track you via cookies and then email you.

Orrrrr... that website is affiliated to another website you have been on and therefore sharing data, could be a number of things.

No, as frankly I have zero trust in Google doing anything about tracking should I try and opt out of it. Beyond adding yet another bit of garbage to the computer!

But how can they have got the email address? I can't see any legitimate way they could do this.

Only options I can see is that some other site has recorded a cookie which they have linked to an email address I have entered there, and that has been matched by a similar 3rd party cookie on this web site. But would need a lot of sites participating to make this have any chance of success. Hence pretty much only with the kind of coverage that Google manages with analytics.

Or the other option is that Google matched up tracking cookies from viewing the site when I had Gmail open in another window of the same browser.

While there might be other options I would expect then to be reliant on browser bugs that would be rapidly stamped on (eg, one browser window being able to access other browser windows).

All the best

Make sure you log out of services like arseface when you're not using them. Those discussion sections that appear at the bottom that have your arseface avatar are the give away that you just told arseface which site and page you've been to. Similar for Disqus n'all that shizzle..

Hi

Work computer and never used Facebook on it.

But Disqus is a possibility which I hadn't thought of.

All the best

By cross referencing many different pieces of information that are either stored in cookies or you have visited a site in the tracking company's massive ad network. Some of these companies are colossal and have tracking on pretty much every website you can think of as part of their ad networks.

They've most likely tracked you via your IP address from a form filled out elsewhere or a cookie. Cross reference that across a lot of data they have from the network and somewhere along the line, you've filled out something or visited one of their websites and they've matched you to your email address. It's not Google Analytics, they do not share this type of information with 3rd parties that will personally identify you, at least not commercial companies anyway.

Cookies are even kind of useless these days in the fight to block websites collecting data against you as even browser installs have unique finger prints. Ad Block even tracks you, which is ironic.

As much as you might think there's no possible way they could have got this, it's far more common than you think.

Hi

I can see how it is possible, just dubious about a large enough cross reference network beyond Google Analytics. Either way it requires a very wide network of cross site scripts, with also a method of allow cross site communication, and further having those scripts having access to form data.

Google analytics is as common as dirt and quite invasive, but not sure of any others which have managed to get into enough sites (and they pretty much need to be added by the site owner) to be viable.

All the best

Mate, seriously, some of these ad networks are absolutely colossal and have their hooks in most websites in some shape or form.

You've been cross referenced, simple as that Thumbs Up

Unless it was magic.
