If you require registration for a low-paying faucet, you can kiss your traffic goodbye. I hate joining sites that require registration unless the risk is worth the reward. For instance, I have no idea what the hell admins will do with my email address, and I hate when I start receiving junk mail from a site without opting into it in the first place. Now when a site asks me to register, I laugh at 'em, especially if they are a low-paying site. And I know I'm not alone when it comes to this.
