Twitter is tracking down stolen jokes and blocking tweets to protect the content from being plagiarised by users.

The incident came into the spotlight when an account holder @PlagiarismBad noticed that five tweets were taken down citing reports from the copyright holder @runolgarun.

According to @runolgarun account owner Olga Lexell, she was the first one to publish a certain joke and said that she filed for removal of the tweet.

For its content, Twitter complies with the Digital Millennium Copyright Act DMCA, and tries to protect the plagiarised content like photos and videos from being spread.

Though the US copyright law does not always cover short phrases including tweets, but Twitter wants to make its platform free from copyright infringement.

The users can make a complaint about copyright violation through a web form platform, following which Twitter employees scan through the application to find any infringed content.

If the copyrighted content is copied without giving proper credit to the creator, then the micro blogging site deletes the tweet, reported The Verge.

Twitter has previously come under fire when companies like GoPro and newspaper giant The Sunday Times tried to remove negative things written about the brands by using DMCA as a protective shield.
