That's very true. That's why I provide generic usernames and everything. Because how the current providers offer service is as through a debt system. You rack up the $$$, and they tell you after the fact.
I would greatly prefer to pay up front, and have services take my credit. That way, I could control my costs directly and concisely. No surprise billing. DOS'es get stopped by no more funds- they aren't the infinite money piggybank they are now with debt.
I also understand why some clients would want a debt based system where they can expand and contract their costs. I'm cool with that, as long as you know what you're signing up for. The person in this article didn't, and surprise billing is majorly at fault here.
My solution would stem this "You owes us $20,000 by end of month", to "Your credit is exhausted after 10 minutes. Something seems wrong with this account cwhen compared to history."
