German Twitter user Shahak Shapira has taken on Twitter over their failure to tackle abusive tweets.

Over the past few months the writer, musician and satirist claims to have reported about 300 tweets featuring hate speech only to see them remain up on the platform so he did what any good activist does and decided to take matters into his own hands by  spray painting the offensive messages on the pavement outside Twitter's Hamburg offices.

In this short video about the project, Shapira hoped to get the attention of the company and while we're not sure it will make much of a difference, it might make some people think twice about what they post online. Twitter has many merits but this is clearly a problem.
