I don't believe anything was rescinded in the situation being discussed; Valve just prevented the user from continuing to use their community/marketplace services. This makes sense because they were put into the bucket containing fraudulent or abusive user accounts.

So what you're saying is I should find a fat juicy data pipe somewhere and download stuff from Steam until I fill /dev/null... ;oP
Seriously the. 15 minutes or so of support time will have cost more than the game did in this case, but it really is the principle. Stealing lots of small amounts from lots of people is still criminally dishonest.
