I downloaded and used Digg on three of our WP sites and noticed after a few weeks that the site were very slow to load.
We noticed that the site was trying to access b.scorcardresearch.com, a site we had no knowledge of.
After hours of investigation and setting our Chrome browser to block all 3rd party cookies, we discovered that these were being action by the Digg Digg plugin. We removed it and the cookies disappeared.
Is this normal practice? We haven't had any issues with other plugins working in this way.
For the record, the plugin wasn't just sending information to b.scorecardresearch but in some instances on our sites and other instances of this on friend's site, 12 or so different market research sites.
Can anyone shed any light on this?
