The problem is 1 person creating 10,000 accounts. Solve that and you will be rich.

Why solve it at all? 10,000 fake accounts for every human is working out great for Elon. =)

Seriously, though - the solution isn't to prevent people from doing this, it is to remove the incentives that encourage it.

How do you remove the incentive? Don't allow free accounts?

[4chandaily]

Don't use accounts at all for non-paid features.
