A man named Shahak Shapira is going viral on YouTube after posting a small protest he made against Twitter's policies regarding reporting abusive users. In his video, Shapira claims that he's reported hundred of racist, homophobic, and abusive comments on both Facebook and Twitter. Facebook is generally very responsive, and of the comments and posts he's reported, Shapira estimates that about 80 percent were deleted. Not so much with Twitter.
He claims that only nine of the 300 tweets he's reported were ever deleted by the company, and in some cases he received no notification, which obscures Twitter's system for deciding what violates its rules and what doesn't. Shapira decided to take just 30 of the abusive tweets he reported and spray them on the sidewalk with liquid chalk outside of Twitter's headquarters in Hamburg, confronting employees with the ugliness online in the real world.
