I see two problems with this strategy: a) New developers still see "60 days" and say "Fuck you!", you should emphasize the shortest available payment schedules on your site (make the "anti-fraud" period seem more like a short hurdle to get over) b) 30 days is still too long for verified publishers; while it's a reasonable "new account" rate (for after your beta period), if I'm verified and doing volume on your service, I expect Net-7 or daily.

But what do I know, I'm just a developer who's looking for a recurring billing platform for my indy service.
