Instagram is the latest social media firm to tweak its app in an attempt to prevent harassment

"Danielle Citron, professor of law at the University of Maryland, welcomes the changes because she said they give users more control over the content with which they interact. She noted that Instagram is merely catching up with policies already in place at Facebook. 

“The most important thing is educating users about what is acceptable on the site,” Citron said. 

She added that tech companies have come a long way in moderating user behavior, but that they can be more sophisticated and clear in their approach to what constitutes harassment."
