You can control who can find you on facebook and access your updates through Settings -> Privacy. They can only be visible to friends, and you don’t need to appear in Google search.
What you put on twitter and facebook can be read by anyone at work; there may be repercussions if your company thinks you are misrepresenting their employees.
In the United Kingdom, contributions made to the Internet are covered by the Communications Act 2003. Sending messages which are “grossly offensive or of an indecent, obscene or menacing character” is an offense whether they are received by the intended recipient or not.
If someone has acted inappropriately online towards you or someone you know, you can report it directly to CEOP. It could be sexual chat, being asked to do something that makes you feel uncomfortable or someone asking to meet up.
The Child Exploitation and Online Protection (CEOP) Centre is part of UK law enforcement and can apply the full range of policing powers in tackling the sexual abuse of children.
Be aware that comments and pictures posted online will be read in years to come by people including new friends, family and employers. If in doubt, ask yourself if the public should be seeing it.
Signing up for Facebook includes accepting the contract of their terms and conditions – which includes the agreement not to bully, intimidate, harasses or to post hate speech. Doing this could result in facebook taking legal action against you, as well as the consequences from the Police of documented bullying.
Facebook’s terms state “You will not bully, intimidate, or harass any user. You will not post content that: is hateful, threatening, or pornographic; incites violence; or contains nudity or graphic or gratuitous violence.”
Facebook has three main tools you can use if you are being bullied on Facebook: Unfriend – only your Facebook friends can contact you through Facebook chat or post messages on your Wall; Block – this will prevent the person from seeing your information, including posts and updates – even if they’re a friend of friends – or contacting you in any way on Facebook; Report – if they’re posting abusive content, report the person.
If you are being bullied on facebook, they suggest you don’t respond, don’t keep it a secret and do document and save the messages.
