Taylor Swift has employed a dedicated team in order to remove all Periscope videos and other unlicensed materials of her concerts from the Internet. The company has been sending numerous letters to Periscope requesting removal of concert videos, most of which were posted by fans.

Taylor Swift doesn't mess around when it comes to aggressively confronting Internet sites she feels are doing her wrong. Last year, she took on Spotify when she wrote an open letter to the Wall Street Journal, criticizing the company for not properly compensating artists for material streamed on the platform and removed songs from the service just as her hit album "1989" was topping the charts.

This year, she famously took on Apple Music with another open letter, lambasting the company for failing to compensate artists during the three-month free trial period offered to subscribers of the company's new music streaming service, Apple Music. Apple backed down and agreed to pay performers during the trial months.

Now, it appears that Swift is going after Periscope, Twitter's new video streaming service that allows anyone with an account to stream live video, which is then automatically removed after 24 hours. Most other performing artists are not concerned about having concert videos posted on the service as the quality of the video and audio is poor and the one-day time frame for each posting is so short. Indeed, most takedown notices for Periscope involve live sporting events.

That isn't stopping Swift, who has a dedicated copyright infringement team known as TAS Rights Management — TAS standing for T(aylor) A(lison) S(wift) — from sending takedown notices to Periscope requesting that videos of her concerts posted by fans be removed immediately. One such notice reads, in part: "I am authorized to act on behalf of TAS Rights Management. I need to request the removal of a live musical performance by the artist Taylor Swift. Below are the URL's ... I have a good faith belief that the use of the material in the manner complained of is not authorized by the copyright owner, its agent or the law. The information in this notification is accurate, and, under penalty of perjury, I am authorized to act on behalf of the copyright owner."
