Prevent php regex, someone using private.php maybe using they bot spammer script

Maybe you could do one of:

- Add human verification to PMs
- Add an extra text field or checkbox to the PM form then check for it before sending a PM
- Rename private.php to something else (you'd also need to find everywhere private.php is used in the code and templates and change those too).

But of course all of those would require some programming, and possible editing of vb files.
