The German has been outcast at the Gunners after a number of defensive mistakes last season.
And after being constantly lambasted by supporters on social media, Mustafi fears for what his children will read about their father in the future.
"Football has become more inhumane," he said. "Social media has also contributed to this, because anyone can comment, without names. People can unload their frustrations directly on us."
"It is no longer about the sport, but only to discredit someone to get as many likes as possible. I would like to see more restrictions in the future.
"What's on the internet will never disappear. And I'm worried that this will eventually affect my children."
