I've been informed by email that my credits will expire in 30 days. I understand that I signed up to iStockPhoto under those terms. I also understand the definition of theft and whether it's in your terms of not, theft is theft.

I don't know why credits expire. I don't know what you gain. If you are looking for me to renew my credits, I can tell you I don't have money. But what I do have are a very particular set of savvy shopping skills; skills I have acquired over a number of years. Skills that make me a nightmare for companies like yours. If you leave my credits alone, that'll be the end of it. I will not look for alternative service, I will not post negative comments on twitter. But if you don't, I will look for alternative services, I will find better alternative services and I will leave you.
