Accepting Emails can be dangerous
Don't open junk mail!
If they have your email address some websites will send you lots of junk emails trying to sell you things, or messages that make you feel uncomfortable. This is called spamming.
Delete any emails from people or companies that you don't know. If you open an email that says rude or unpleasant things, you must tell a trusted adult straightaway - and don't repy to it.
Always tell an adult if you feel uncomfortable or worried!
Some message boards and chat rooms have an 'alert button' or an email address where you can tell the 'host' (who runs the board) that you're upset about something or someone.
Don't forget you can always log off and leave the website.
