Dear Jack and Mark,
As recent weeks have seen the levels of vicious, offensive abuse from users of your services aimed at footballers and match officials rise even further, we write to ask that for reasons of basic human decency you use the power of your global systems to bring this to an end.
The language used is debasing, often threatening and illegal. It causes distress to the recipients and the vast majority of people who abhor racism, sexism and discrimination of any kind. We have had many meetings with your executives over the years but the reality is your platforms remain havens for abuse. Your inaction has created the belief in the minds of the anonymous perpetrators that they are beyond reach. The relentless flow of racist and discriminatory messages feeds on itself: the more it is tolerated by Twitter, Facebook and Instagram, platforms with billions of users, the more it becomes normal, accepted behaviour.
