When looking at someones profile I noticed that they had a number of visitor messages that had a fair amount of private information exchanged. When you use the visitor message function the messages will be visible to anyone who looks at your profile. From the FAQs:
What are Visitor Messages?
Visitor messages are publicly viewable messages posted on member profile pages. To post a message, click on the 'Visitor messages' tab, and use the form at the top of the section. You will only be able to use certain formatting in these messages, as described underneath the edit box. This message will be viewable by all visitors to this profile, including guest users and search engine robots if the administrator has allowed this. To communicate privately with a member, send a Private Message instead.
Visitor messages can be edited or deleted by site moderators or the member who owns the profile. If you see a visitor message that is not appropriate, you can alert the moderators by clicking on the 'Report' link. The 'View Conversation' link allows you to view all visitor messages between the member and the owner of the profile.
