Ok, I'll put it another way. I'm some extremely large number percent more likely to be an early adopter of your product than my mother. I will never, ever sign up with such a restriction on my password.

I don't care what we do about the rest of them. Make a bigger black list, require more complex passwords, implement better protections against brute force.

The easiest one (to use and implement) is two-factor auth, but many people lack smartphones still so it's hard to make that the easy call.
