well i'm just interested from the point of view of a web page being able to lead someone to being charged a lot of money without them realising that they were being impacted.
Me too :-)
The thing is, we are all dependent on others generally doing the right thing, which this guy isn't.
If even a significant number of websites behaved this way, the web would essentially become unusable since we'd all be consuming bandwidth at about 1GB/hr, just browsing web pages.
If this guy has 1,000 viewers, he'll be supplying data at 1TB/hour, serving what might as well be a static page. Bet he's not paying for his bandwidth!
I think we really need tools (preferably automated) to deal with these kinds of situations. Usage alerts would be a big help. This kind of thing is going to become more of a problem as network speeds increase, and more always connected devices come into use.
