Hrm, my idea is similar to Moongods I suppose. I didn't bother reading this thread, so excuse my ignorance.
Trial accounts are changed from 'limited' accounts to 30-day based accounts. They can play with their newly made 30-day trial account with no limitations. After the 30 day trial is over, their account becomes disabled until it is upgraded. They wouldn't be allowed to create a new trial account either, because the website would log their IP and block it from making future accounts.

This way, they either pay... or no play.
