Weston’s school superintendent on Wednesday advised administrators throughout the system to talk to students about social media safety amid concerns that someone used a fake Snapchat account to solicit sexually explicit pictures from high school boys.

Superintendent Robert Tremblay said the investigation continues into who sent the sophomores the requests. Weston High School principal Anthony Parker previously told parents he had received reports that some boys “may have responded by sending compromising pictures.’’

Tremblay said he was using the incident as an opportunity to teach students to be wary of what they are sending via digital communication, and who might be receiving it.

He said he hopes the case helps students and families “have meaningful discussions about using the Internet.’’

The high school held an assembly for all sophomores about the matter on Tuesday, but on Wednesday Tremblay said he had asked administrators across the public schools to create opportunities for discussion about how to be safe online.

Tremblay said he believes the person soliciting pictures was using Snapchat with what appeared to be a fake name. Authorities have not determined the person’s age, gender, or location.

Tremblay said kids, including many below the high school level, are constantly chatting with friends, sharing pictures, and posting videos — often in the pursuit of “likes’’ and views.

“It’s just a way of doing business when you’re a teenager. You just have this instant feedback mechanism,’’ he said.

Students sometime share without “really caring who’s liking it, just that people are.’’ That “almost becomes a numbing factor, where people aren’t really considering the audience,’’ Tremblay added, “and that can be dangerous.’’

Weston police, who are handling the investigation, did not respond to a request for comment.

Snapchat is a service that allows people to edit and share photos and videos, which eventually “disappear’’ from the platform. But Parker said in a letter to parents that deleting a file “does not mean it really goes away.’’

“They continue to exist on the service provider’s network and can and have been obtained for legal proceedings,’’ his letter said.

Snapchat declined to publicly discuss the Weston case, but the company has previously said it cooperates with law enforcement and complies with valid law enforcement requests. The service also investigates users’ reports of abuse, and works with online safety organizations.

Elizabeth Binney, a parent of two Weston High School students, said the case has underscored for her the importance of having family conversations about online standards.

“This is the kind of stuff we worry about with social media, so I can’t say it’s new,’’ she said. “You just have to keep talking with your kids.’’
