Good riddance. The amount of scams in the long distance industry was baffling. Legend has it one of the companies named themself "I Don't Care" so if someone said that when asked which long distance carrier you wanted, that's who you got with their ridiculously expensive rates. Calling cards were just an extension of the same idea.
Not much has changed there, apart from the sheer scale: the amount of scams in the internet industry is truly baffling!
