The subject of this blog entry probably doesn't make sense, that is, in a sensible world. After all, how can something that's legal be a scam? Apparently credit card companies that previously offered cardholders high limits can lower them without cause, resulting in fees for exceeding the credit limit.
I haven't been a "victim" of this (yet) but when I read this article, it made me want to check all my credit card limits. I just don't see how this practice can be legal or even possible, unless the cardholder misses a payment.
