Anything you post online, anyone can see – friends, family and even not-so friendly people. Think before you post.
Once you post your picture online, you can’t take it back – anyone can see it, anyone.
You can’t “take back” the online text and images you’ve entered. Once online, “chat” as well as other web postings become public information. Many web sites are “cached” by search engines, and photos and text can be retrieved long after the site has been deleted.
