Twitter, Facebook and Instagram platforms are "havens for abuse" according to soccer's governing bodies in the UK, who today urged the social media companies to tackle the problem in the wake of racist messages aimed at players.
In a joint letter addressed to Twitter CEO Jack Dorsey and Facebook CEO Mark Zuckerberg, the Football Association, Premier League and anti-racism organisation Kick It Out said the levels of abuse aimed at footballers had risen in recent weeks.
"We have had many meetings with your executives over the years but the reality is your platforms remain havens for abuse," the letter read.
"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.
"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."
Manchester United's Axel Tuanzebe, Marcus Rashford and Anthony Martial, Chelsea's Reece James, West Bromwich Albion's Romaine Sawyers and Southampton's Alex Jankewitz have all been victims of online abuse in recent weeks.
The governing bodies, which also included the English Football League and the Professional Footballers' Association, demanded that messages and posts on social media be filtered and blocked if they were found to be racist or discriminatory.
They also asked social media firms to conduct a verification process, if required by law enforcement, for all users for accurate personal identification and to stop users from making new accounts if previously found guilty of online abuse.
"We call for meetings with your organisations to discuss the evidence of abuse on your platforms, the action you are taking, and how you plan to directly address the matters," the letter added.
Instagram on Wednesday announced a series of measures to tackle online abuse, including removing accounts of people who send abusive messages, and developing new controls to help reduce the abuse people see.
Twitter said in 2019 that "vile content has no place on our service" after it took action on more than 700 cases of "abuse and hateful conduct" related to soccer in Britain in two weeks and promised to continue its efforts to curb the problem.
In Ireland, former Arsenal player Ian Wright said he was disappointed that his forgiveness of online racist abuse which he had received from a Kerry student Patrick O'Brien had been used as "an invitation to lighten a sentence".
