Facebook encourages care by offering teenage girls middle-aged men as "friendly proposals," the media reported.
Teenage girls under 13 who have joined the social network give up to 300 suggestions about who they can add to their friends, including middle-aged men who are overwhelmed in their profile pictures, The Telegraph reported late on Saturday.
Facebook has said it was not a typical experience for teenagers who had signed up for the service, and that it has the protection features built into its recommendation system.
Based on the findings, the National Society for the Prevention of Child Cruelty (NSPCC) has been urging the Friends of Children to Stop the Social Networking Giant Forum.
"Groomers seeks to infiltrate child friendship groups into social networks, often with the aim of transferring children to live streaming or encrypted sites where their sexual exploitation is easier", says Andy Burrows, Deputy Chief of NSPCC.
"The risk of social media algorithms is that custodians will find and contact children, and" friend friend "or" new follower "recommendations can increase the legitimacy of their requests, which is why we demand that these features be prevented.
"Too long social networks have not been able to create safe platforms for children, and therefore the home segment needs to commit to strong and effective regulation to ensure that child safety is not negotiable," he said.
According to Facebook, the company has protection to protect its children. However, campaign troops warn that networking giants must do more to prevent site users from becoming friends with children.
"Grooming is incredibly serious, and we have teams that focus specifically on safe child retention, broad-based research, and outside experts," said Daily Mail, a spokeswoman for Facebook on Saturday.
"We use artificial intelligence to proactively detect cases of inappropriate interactions with minors, and refer to possible abuses in law enforcement.
"We limit ourselves to finding children in search, reminding them to only accept friends' requests from people they know, and we warn them before public messages."
In October, Facebook had removed 8.7 million user IDs from using infertility using previously unstructured machine language learning that automatically tagged such images in the fourth quarter.
The company has reported that it will also consider the use of developmental systems to detect infertility and care for Instagram.
