The WASPS and MTN make so much money from these subs services and multiple SMS services that they can just laugh, take a slap on the wrist and pay the (small) fines.
Another big bugbear is spam, which I now get every week from. Algain, MTN gets so much money out of it they have no reason to seriously try to stop it. And to try to stop it, you have pay for yet another SMS to reply (which doesn't always stop the spam anyway).
My other bugbear is those misleading competitions, like the MacDonalds Quarterpounder, "buy the combo meal and win a ticket to 2010". Well, you pay your money, buy the meal and end up with nothing but a code that you STILL need to SMS to a premium number to enter.
