So this will allow a new forum the ability to add thousands of users to their site, that don't really exist, to make their site look as if it is more active than it really is? You may want to mention to those thinking this is a great feature that if your site says it has 10,000 users and the site only contains 300 threads or posts, your site will not look "great", but rather like you have a ton of users who do not post.

Anyone who uses this feature needs to do so in moderation. It isn't something I would ever use (I wont unleash the drama aspect) but those that do should keep in mind the ratio of posts to users that they have. A site with thousands of users and no activity is worse than an active site with fewer users.
