What should I be concerned about on Facebook?

[Sheridan]

no not really, with facebook there is alot of personal stuff on there. so to tackle this problem just add friends...most people just add everyone and this puts them in danger. Another thing to worry about is likes, you can like pages and they just keep posting pointless rubbish so be careful about what you like. Dont allow access of facebook on your phone because some people regularly get their phone nicked and people post stuff on your wall. Put up your facebook security up to a high level so only some people can see your profile and only certain people can send you messages because some people just send random messages which is quite annoying. Errmm besides the above nothing much else to worry about
