I'm fairly certain they'll double it or more the minute you ask them, maybe a couple of times before scrutinising it. Posterous had the same thing btw, with a limit of 3 blogs, and they increased my limit in a few hours.

I've implemented the same kind of workaround, and for two reasons.

It's actually a lot easier technically. I mean DB already has a limit for free users, so all they have to do is rev up the limit and all their clients "just work". They don't have to add magic if-then logic to change how clients show and enforce the limit.

Secondly, it prevents a disaster scenario where some script - either malicious or accidental - smashes your monthly quota with 1s an 0s. Yeah you could try to rate-limit it or something, but it's just easier to prevent the whole scenario by changing a database column.
