When you allow geotagging with an image, you are allowing a website to see the location information for a photo/video you've taken.
Be cautious when providing this metadata. You might just wind up on http://iknowwhereyourcatlives.com/.
Every photo on this site was created and uploaded with the locational metadata intact by the original owners with an estimated 7.8 meters accuracy. It's scary that you might give random strangers access into your house. Turn off your geotags.
It may not be the best idea to give away your location when posting a picture.

Give credit to your sources.
When creating projects, please remember to cite all of your sources including quotes, videos, text passages, and music.
Go with your gut.
If anything makes you feel uncomfortable online, while gaming or when using your cell phone, talk with your parents or guardian right away.
