Skype is pretty much the only service, I know of that denies business to its own customers.

What will happen if you buy lots of SkypeOut minutes? You think, what happens everywhere else - Skype will reward you as a loyal customer, right? Nope! Don't even dream about that. THEY WILL BLOCK YOU.

The following is Skype's "justification" of why:

" In order to reduce fraud we restrict the number of times you can use a specific payment method per month. The reason for this is that the most common method of fraud is to use a stolen credit card or Paypal account many times in a short time span. By limiting the number of times you can use these payment methods per month we can significantly reduce fraud."

Rarely heard anything more stupid.

Dude, wake up! Half of world's business is online, nobody denies frequent customers!!!
