"bad mouthing buyers or sellers"... "deceptive sales environment"... "establishing fake verified-status identities"...

So how is this different from what happens on the internet all the time, right now?

A market is a market any fiddling tools are going to end up in the hands of the criminals and governments these boffins need to be held responsible for any damage done legitimate commerce by their tools possibly jail time when the inevitable happens.

It is only a matter of time until someone co-ops these tools and uses them to disrupt "legitimate" markets, ebay, etc.

Those techniques could be viewed as breaking the 2006 Fraud act. So employing them here could result in jail time.

Not strange at all. At most a credit card number is worth say AUS$5,000 which is an average credit limit. More likely you'd get $1000 then the banks start noticing and phone you (mine does anyway).

One single MP3, according to the RIA Ass. is worth $4.7bajillion (with Dr.Evil finger in mouth) or seems to be the way they sue...

Its obvious. when you download an mp3 you are "stealing" from a business. when you steal a credit card number you are only stealing from another peon. anyone can steal from the masses and nobody cares, just ask benny hin. just dont steal from the ruling class.
