The Internet can Record Everything You Put on It
What ever you put on social media will stay there. Even if you are on something like snapchat, people can save your picture. When you delete a photo from social media, people can still find it.
Be Careful About What You Put on the Internet
When you put a picture on the internet or social media, it is very hard to delete it completely. Even if you deleted the photo on your page, it can be found in other places. If you put an embarrassing photo of a friend on social media, you could get in trouble with your friend, even if you think it is funny.
