Hi Matt & thanks for the reply. Much appreciated!
Do you mean disabled by an end user or the website owner?
If stat tracking can be disabled, is there any other tracking going on once stat tracking is disabled by the website owner?
And what do you mean by validation, exactly? The W3C validator?
Yes, the w3c, sorry for the lack of clarity.
... should you so choose, and in our analytics interface on AddThis.com with more detail.
Is this info available publicly or only to the website owner via login? There is another popular sharing plugin out there that unfortunately reports this data publicly!
