Earlier quoted context omitted.
Meh. I wasn’t going to bother getting a lawyer involved for a balance of a few thousand dollars. I did threaten legal action though it proved futile. Out of curiosity, why was it not a good course of action? Did the client have any leverage after being 6+ months past due on their payment?
I was more referring to the $30k example above. In your situation probably fine for a few thousand, but if someone owes you a significant amount of money then I don't think you should act in this way. You just sue them (if all else fails).
What is your rationale? Netflix suspends your account for non-payment, the same should apply to web infrastructure.
