Make sure you are of age in the website. If you are too young, don’t join it. Bad people can go on these sites and search you up. Age restrictions are there for a reason!
Always make sure you send appropriate posts. A good way to check is… if you wouldn't show your parents what you’re posting, don’t post it!
Make sure the only people you befriend are people that you know in person. If you befriend someone you don’t know personally, or haven’t seen in person, they might be a terrorist!
If you put personal information (e.g. the name of your school) on your profile, bad people might gather that information, and come to our school (for example) because they know there are kids there.
