I have recently implemented one of these wasp services, sending out SMS's charged at R5. We adhere to the waspa rules, and have things in place that should a billing attempt fail 3 or more times in a row the user is automatically removed etc. But it is vey easy to actually ignore the rules and just bill any cell number you can find. I'm not surprised that people do this. I fact I was billed by "loadin" something like R20 for three months. It was when that service started and I think I was "optet-in" as defult when they started. Are you aware that the cellphone operators pocket something like 33% of the charged amount? They must be making millions, and that is probably why they don't do more to prevent this sort of thing.
loadin = Buongiorno, one of the scoundrels mentioned in the article. They've recently bought Itouch, can understand them wanting a bigger pressence in a country where it's this easy to milk consumers.
