Assuming you can build such a test.  Good luck.

If it's arbitrary, it's generated by some algorithm.  If it's generated by
some algorithm, I just need to figure out the algorithm and I can always
get it.

If you've got a database mapping arbitrary number/name/string to an email
address, then why not just have a web form that sends mail to that address
knowing only the arbitrary value (and never divulge the email address)?

I don't believe any system like slashdot's is worth the time to implement,
since it is just as easily broken, and now you've got more useless stuff
for every single user to manage.
