Allow multiple free accounts?
gojomo: Tread carefully; in some cases it might legitimately be two users behind the same NAT or on the same computer.Or, people whose main motivation isn't avoiding the payment but getting some other benefit -- two identities? -- from two accounts. In which case, making sure a single paid account has the same benefits could help.If you start to crack down, you might want to mix it with a bump-up in free quotas. "Even as we are more generous with our free accounts, we need heavy users to subscribe..."It also sounds like the population is large enough to try some A/B approaches to get them to sign up -- more steps in logout/login (if they're using a single browser), an option to merge accounts, interstitial upgrade appeals, etc.
