Personal integrity? What's that?
You know.. they might be sending passwords or other confidential information through PMs.. imo, it's bad enough that the passwords are stored as plaintext in the database.. there's such a thing as becomming paranoid & monitoring everything your users do..
for instance, most people probably use the pass they have for your forums as the pass they access their email with.. if you want to monitor what your members say & do, why not take it a step further? why not log in to their email account and see if they talk about you there?..
