Facebook Tips: Block and Report Spam

If your Facebook Privacy is not set very high, you may receive chats from inappropriate users or spam. You can no longer Block them from here…but you can mark them as Spam. To block someone, click your privacy settings and add this person to your restricted list.  

Click on the Go to conversation command in the bottom right of your Chat window. Your chat will open in the Messages pane. Click on the Actions menu and select Report as Spam.

You can also click on Report in the Chat window to automatically report the chat as suspicious. Remember to delete a Conversation if it is of a discrete nature. Facebook automatically saves every single one of your chats and messages. 

For extra security, you may want to delete your chat history.  Click on the Go to conversation command. Your chat will open in the Messages pane. Click on the Actions menu and select Delete Messages.

Determine which messages you want to delete:

 To delete the entire conversation, select Delete All. A confirmation window will appear, click Delete Conversation. To delete part of a conversation, select the messages you want to delete and click Delete Selected. A confirmation window will appear, click Delete Messages.
