Hi Tom:

If you open the DNT+ t you will see the 3 icons (social networks, ad network, and companies)

Clicking on an icon will tell you who is doing the tracking.

Right now while I am on SOWPub I have 5 trackers blocked.....no social...1 ad....4 companies - 2 of which are Google.

Also the 1 ad is from Quantcast and after reading about them I think it may be coming from the hosting server for SOWPub.

Chartbeat...is an analytical script that may be monitoring the forum activities ...at least that is what I am taking from their web site.
