That's a trivial problem to solve. Simply don't even mention you're the founder. Or demote yourself to a tech lead, or someone. It's only a problem if you glamorize yourself and jump and shout to everyone that you're the founder of so and so.
Yeah but simply mentioning his association with a project will lead to 10s if not 100s of thousands of users basically instantly. They're just not the kind of users who you can monetize easily.
Having Christopher Poole as CEO probably helps raise money too.
There's also a question of ego, greed and fear-of-failure here. I mean, I can imagine it being pretty damn hard to ignore the fact that you have a "Gain 100.000 Users Instantly" button(that being a tweet, blog post or whatever), right at your finger tips.
