You can say things that you like to do, but personal information should not be shared. This includes names, schools, addresses, phone numbers, and email addresses. These should be reported. It has been stated that it is okay for Scratchers to post pictures of themselves with a parent's permission and to make sure they're alright with what they're posting. [citation needed]
This rule is in place mainly to protect the majority of users who are minors using the website.
