however the code you supplied, having been placed in said box, is not working - the tracking pixel remains despite various cache emptying etc.
I'm also not sure what you mean by the Lockerz tracking being 'normal'.
Having googled the line of code you supplied, I see I'm not the first to raise the privacy and disclosure issues.
The tracking pixel and media6degrees cookies have been variously called "spying", "behavioural marketing" etc etc.
Given the number of add to any users I can understand the temptation to gather this data which I presume yields significant revenue.
However, it seems to me that a failure to disclose this openly to plug-in users is unwise at a time when internet privacy is a growing concern.
It's a great plug-in in terms of its functionality, but I'm not comfortable that my readers are being tracked without their knowledge or my permission.
Not to mention that the tracking pixel is adding to loading times on my site - despite it being only 1px x 1px the server seems slow on occasion - no doubt due to the millions of hits it's taking as it happily gathers all that $data.
Can you suggest why the line of code you supplied might not be working?
