Twitter Beginning to Filter Suspicious URLs?

Back in March we blogged aobut how URL-shortening services could pose a threat on social networking sites such as Twitter. The Wall Street Journal blog is now reporting that they may be doing something about it.

Although Twitter hasn't officially responded, the blog is reporting that tweets with links to suspicious sites will be deleted, with a message "Oops! Your tweet contained a URL to a known malware site!."

While I have not seen such tweets or messages, it's encouraging to hear that although Twitter may have many other issues to worry about, they are taking security issues seriously. If they wish to become the dominant player in the marketing and microblogging space, then they need to be a responsible citizen regarding security on the Internet and for their users.
