ESecurity Planet reports on an interesting privacy question at Twitter:
By the end of the year, Twitter plans to roll out its link-shortening service, t.co, across the site, meaning that every Web address shared on Twitter or its third-party applications will be wrapped in that format.
Twitter’s own link shortener competes with similar services, such as tinyURL and bit.ly, but boasts a security advantage because it displays part of the original URL. Other shortening services obscure the destination Web address, a feature that scammers have taken advantage of to direct unsuspecting users to malicious sites.
But as part of the t.co roll-out, Twitter said it will begin logging every link that users click on its site and third-party applications, provoking a fusillade of tweets from users raising questions about the privacy implications of the new feature.
“Seriously @Twitter the link hijacking plan stinks of Facebook style privacy intrusions,” user @cheezeball73 tweeted.
