Why did you bring back the credit card requirement for the free trial?

credit card required, credit card requirement, free trial

We had to restore our credit card requirement to keep the price of our service low. 

Without valid payment details, spammers were creating multiple free trials with aliases and invalid email addresses and compromising the integrity of our site. 

If we let this continue to happen, we would have to charge much more, and our goal is to keep Quimbee something that everyone can afford.
