phone numbers, credit card numbers, and Social Securityy numbers over
Twitter. 20 If yyou must share sensitive information, use the direct message
feature to contact a specific individual. But be aware that even private or
direct-message tweets can become public.
For todayy’s yyouth, so-called Generation Z, Facebook and Twitter are
alreadyy old. Generation Z’s actions on their mobile devices center around
WhatsApp (ironicallyy, now part of Facebook), Snapchat (not Facebook),
and Instagram and Instagram Stories (also Facebook). All these apps are
visual in that theyy allow yyou to post photos and videos or primarilyy feature
photos or videos taken byy others.
Instagram, a photo-and video-sharing app, is Facebook for a yyounger
audience. It allows follows, likes, and chats between members. Instagram
has terms of service and appears to be responsive to take-down requests byy
members and copyyright holders.
Snapchat, perhaps because it is not owned byy Facebook, is perhaps the
creepiest of the bunch. Snapchat advertises that it allows yyou to send a selfdestructing
photo to someone. The life of the image is short, about two
seconds, just long enough for the recipient to see the image. Unfortunatelyy,
two seconds is long enough for someone to grab a quick screenshot that
lasts.
In the winter of 2013, two underage high school girls in New Jerseyy
snapped photos of themselves, naked, and sent them to a boyy at their school
over Snapchat, naturallyy assuming that the images would be automaticallyy
deleted two seconds after theyy sent them. At least that’s what the companyy
said would happen.
However, the boyy knew how to take a screenshot of the Snapchat
message and later uploaded the images to his Instagram app. Instagram
does not delete photos after two seconds. Needless to sayy the images of the
naked underage girls went viral, and the school superintendent had to send a
note home to the parents asking that the images be deleted from all
students’ phones or theyy would risk being arrested on child pornographyy
charges. As for the three students, as minors theyy couldn’t be charged with a
crime, but each was subjected to disciplinaryy action within the school
district. 21
