and isnt it possible that they got wind of it through this email that is circulating and just didnt bother checking facts ???
ICSTIS shut down the number in the original scam, and although it is possible (and maybe quite likely) for someone to change the number to point to a current premium rate number, and adjust the scam a little, the £15 fee is a myth. The Bristol media might want to check with their counterparts at BBC Wales who broke the story in 2005 !!!
On one of the links above (first one I think) it says "the claim that an immediate £15 fee was charged as well as the per minute cost is unfounded. ICSTIS notes that, "the reference to £15 is an urban myth. It is not possible for a £15 charge to be made on connection."
