There's not a lot you can go to stop online identity theft unfortunately, all you can do is take the necessary precautions such as making sure your passwords are written down or stored anywhere and also don't tell them to anyone. When choosing a password it's worth remembering that software can do 'dictionary attacks' which try's a number of 'words' until it gets the right one....you're better off with passwords that don't make sense to anybody other than you. If you do fall victim then contact Cybersmile straight away.
Good advice Suzanne and well done for alerting GamerGirl to the dangers of dictionary attacks on passwords. A good way to create new passwords is to think of a sentence and use the letters at the start of each word, adding capitals and numbers instead of letters - make sure it's a sentence which you remember though!
That's great to hear Marti, changing your passwords frequently and not using family names, birth dates or anything too obvious will help you to stay safe online. I gave some really useful advice about how to set a strong password in my comment earlier in this topic.
Perfect Dolphintiger12! Great to see you've got the hang of creating strong passwords. Try and replace letters with numbers too, that will make it extra safe! I actually think that this subject should have its own topic as it's useful for everybody to share ideas.
This can happen SuperDad, but usually there are systems in place to combat this. On the larger social networking sites, you may have to prove your identity in some way but you should get your account back :)
Always be sure that you're contacting someone through a legitimate channel however - don't be sending your ID to just anyone!
Everyone is right, there is no way of stopping people pretending to be you on social media but there are ways of proving which is the legitimate account if it ever came to point that it needed to be proved. My social media is all private so you can't see anything unless you're a friend. If a company came up to me and claimed they saw something I'd be like, well you can't see my profile so you're looking at the wrong one! Obviously have to prove that, but there are ways.
Also dictionary attacks is a method of brute forcing and they compare them to something called a rainbow table ;) Most big websites have things to stop this kind of attack such as so many login attempts. I'd link you to a really good video how password length is more important than complexity but not sure I can!
