This was to be expected, I mean even if a service is laid back in the way they enforce the rules at some point they are going to do it if they see the abuse from their clients is too high, it seems that for you it was worth it to do this but there are many people which would have never done it, either because the possible gains were too low or simply because they will never think about abusing the good will of a service like that, anyway it seems that you will have no option but to find a legitimate way to earn some money online, something which is not difficult to do these days.
