I have set var addthis_config = { data_use_cookies: false } as part of my site's head tag Javascript, but recently I've noticed AddThis is now setting a single cookie: __atuvc containing a value ("2|19" when I just looked)... how can I stop this cookie being set as I've already asked AddThis not to use cookies.
I'd say that the __atuvc cookie is required for the core functionality of the AddThis counters. Without it they won't show the correct count until our caches have been updated. I've got a meeting with our team today to discuss this.
