The Supreme Court of Canada rules web links not illegal‎

The Supreme Court of Canada ruled that hyperlinking to libelous material does not constitute publishing the material itself. continue reading:

Extract:
The ruling will alleviate fears that holding someone liable for how they use hyperlinks on websites, personal ones or others, could cast a chill on internet use.

The responsible use of the internet and how traditional defamation law applies to modern technologies were at issue in this case, which was watched closely by media organizations and civil liberties groups.

How someone can protect their reputation in the internet age when content is passed around with the quick click of a button was also considered in the case. On social media websites such as Facebook and Twitter, users often share links, and the court's ruling could have dramatically disrupted that function had it gone the other way.

CBC.ca - ‎Oct 19, 2011‎

Extract: Wayne Crookes, a former Green Party campaign manager, sought damages from Jon Newton for defamation over links that appeared in an article posted on Newton's website on July 18, 2006.

Newton didn't repeat the allegedly defamatory remarks on his site, but links to two U.S. websites were posted without comment.

The B.C. Supreme Court dismissed the case saying links are like footnotes, not publication. Crookes's lawyer says linking to a website is an invitation and encouragement to visit the site.

Looks Can Be Deceptive: Web Analytics & Transaction Log Demystified

A quote from the book helps visualizing the true figures of a Website's visitors:

"One could legitimately wonder if the counted visits appearing in Table 7-6 can be attributed to actual people or to robots, spiders, crawlers and the likes. Robots are usually small applications designed to gather data for search engine indexes. Unfortunately, the record of a virtual visit by a robot, spider or crawler looks no different in a Web server transaction log than that of a visit by an actual person. Robot visits may be traceable through name identifiers (i.e., Googlebot), or by a high volume of pages accessed in a very small timeframe, or by their requests for a file on the Web site called 'robots.txt.' The latter normally describes what may or may not be indexed from a given Web site by search engines. Nevertheless, if found, visits by robots must be systematically filtered and separately counted or just ignored when assessing the real usage impact of a Web site."
