All About Pinterest
Pinterest privacy
It's important to realize that with the exception of your secret pinboards, anything you pin on Pinterest is completely public. While Pinterest is certainly less revealing than more personal sites like Facebook, it doesn't give you very much control over your privacy settings. Because your pins are public, some people could make certain assumptions about you based on the types of things you pin. Always use your best judgment when pinning things to Pinterest. Never pin something obscene or overtly offensive, which can result in the termination of your Pinterest account.
Copyright, fair use, and pin etiquette
Pinterest has recently faced some criticism about the way the site works, specifically in relation to copyright law. The issue lies in the fact that some pins are not accurately linked to their original sources. You can prevent this by making sure your pins always link to their source, which gives credit to the original creator of the content. If possible, make sure you have permission to pin someone's work, especially when pinning a photograph. You should also take extra care when repinning to ensure the pin is properly linked to its original source.
Some websites even block Pinterest, making it impossible to pin things from that page. You should always respect content holders' right to stop you from pinning their work.
