The leaders of English football have asked the heads of Facebook and Instagram to show "basic human decency" by taking more robust action to eradicate racism and for users' identities to be verified.
There has been growing outrage that players throughout England, from the Premier League to the Women's Super League, have been targeted with abuse on Twitter and Facebook-owned Instagram.
"The language used is debasing, often threatening and illegal," the eight English football leaders, including from the Football Association and Premier League, wrote to Twitter CEO Jack Dorsey and Facebook chairman Mark Zuckerberg.
"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."
Manchester United players Marcus Rashford, Axel Tuanzebe, Anthony Martial and Lauren James have in recent weeks suffered online racial abuse as well as counterparts from other clubs.
"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 letter to Dorsey and Zuckerberg continued.
"The targets of abuse should be offered basic protections, and we ask that you accept responsibility for preventing abuse from appearing on your platforms and go further than you have promised to do to date."
The officials want messages to be filtered and those containing racist and discriminatory material be blocked from being posted.
They also want an improved verification process that ensures users provide accurate identification information and are barred from registering if banned.
"Many footballers in English football receive illegal abuse from accounts all over the world and your companies have the power to bring this to an end," the letter states.
