I'm not sure it's so deliberate either - but I think that's what their strategy should be, at least. By the way, the number 5,000 is a great number: it doesn't really matter what the number is, as long as there is a ceiling, it's pretty clear that you're not supposed to add anyone and everyone. On the other hand, 5,000 is large enough that most users won't realistically hit it.
