Безопасен ли s7.addthis.com?

AddThis is extremely useful for bookmarking. This s7* website is an AddThis sub-domain. The only problem with AddThis is tracking cookies. AddThis doesn't make decisions about tracking cookies. Instead, it is the bookmarking services e,g. Delicious, Twitter, Digg, Reddit, Diigo, TypePad. Some use one (or zero) tracking/cookies. Others place a lot, as many as 20! That is my only, but quite important, concern about this helpful service.

This is a script server for AddThis. It hosts a script (/js/250/addthis_widget.js) that, when loaded onto a Web page, allows web developers to use the AddThis script functions. The script MAY be considered malicious, since, if the webmaster has registered for the AddThis analytics service, it records what service you have used to share a website. This does not indicate that it loads any badware onto machines or tracks your behavior; it means that it simply takes a note that you shared a website with a certain service.
