Twitter’s all-new live streaming app Periscope might be great for journalists to cover an event and for celebrities to get in touch with their fans, but it’s also becoming a magnet for copyright violations.

According to Twitter, it has received 1,391 notices under the Digital Millennium Copyright Act for illegal streams on Periscope during Q2 2015. The number of takedown requests has grown massively from just 17 in April to 833 in June.

Periscope complied with 71% of the takedown requests, amounting to 1029 streams affecting 864 accounts. The app now has 10 million active monthly users and it seems that as the number of users increases, so do the takedown requests.

It became clear how easy illegally live-streaming events on Periscope was when the boxing match between Floyd Mayweather and Manny Pacquiao in May was all over the app. CEO Dick Costello even tweeted “And the winner is…  @periscopeco” at the end of the match.
