When running a web page speed analyzer on a page using AddThis, one can see a lot of "unused CSS" warnings, concerning the massive amounts of CSS that AddThis brings, but are never used.
For example, check this report, http://gtmetrix.com/reports/blueseed.co/iFykSAVU, and click to expand "Remove unused CSS".
About 40% of the CSS on our homepage is from AddThis and not used.
Is there a way to prevent this CSS from loading?
