A new, persistent web-tracking technology developed has been used to track web users across many of the world’s most popular websites, including those of the White House and even wholesale smut platform YouPorn.
The canvas fingerprinting technique was described in 2012 by University of California researchers (PDF) as a means to silently track the web sites users visit. Surveilled users watched over by canvas attacks cannot defend themselves by clearing the tracking mechanism by normal browser flushing nor guard against infection using apps like AdBlock Plus.
If you use AddThis in any of your websites, make sure you remove it ASAP. This is nasty stuff if you care at all about your privacy (or the privacy of whoever visits your site). Also, check out Ghostery, a browser plugin that blocks widgets like this.

levels of headcanon:
- This is heavily supported by text/subtext and is likely what the creators intended for me to get from this
- this is sort of supported by the text and could, conceivably be what the creators intended for me to get from the text/subtext
- there is no evidence either way
- there is slight evidence against my headcanon, but I don’t care
- I’ve stopped giving a shit about canon
