Using a plugin on the register_addmember_process hook, call vB_DataManager::do_unset with "email" as the first parameter. Then, use vB_DataManager::set to set a fake email address.

It should look something like this:

PHP Code:

$userdata->do_unset('email');
$userdata->set('email', uniqid() . '@example.com'); 


After that you just need to remove the email input from the registration templates.
