Social media is all about transparency. It's about sharing and being your authentic self. Uh-huh.
Well, there are some things you should probably keep to yourself.
Here are 10 of them:
1. Your phone number.
There are creepy, disturbed people on the Internet with ill intentions and bad manners. They are called telemarketers. Don't feed them—especially after midnight. It's sort of like "Gremlins."
2. Pictures of your credit card.
Yes, people actually do this. I know you're proud of your new VISA card branded with the Toronto Maple Leafs logo, but showing it off on Instagram is like asking for identity theft.
3. Pictures of any bodily function.
I know where you think I'm going with this, but I'm not. I'm talking about potty training. This is one instance where "take a picture or it didn't happen" doesn't apply.
4. This video:
5. An invitation for someone to rob you.
Letting the one-sixth of the human population that is on Facebook know you're in Mexico this week while that brand new 60-inch TV you posted about last week is home alone is an invitation for someone to rob you.

6. Vague posts.
"Wondering why …"
Me, too. Unfollow.
7. Your password.
This should be at the top of the no-brainer pile. If your password is the name of your cat who has a Facebook account with 1,632 friends, you either need to change your password or the name of your cat.
8. Anything that happened in Vegas.
This is a rule for a reason.
9. Your Klout score, or any other social media statistic.
If you post your Klout score, you're clearly overcompensating for something.
This leads to the final thing you should never share on social media:
10. A naked photo.
If you're an A-list celebrity taking nude pictures of yourself with your iPhone for your PR firm to leak to the media, that's fine. Otherwise, not cool.
