While interesting, I don't think this will become a norm. This is an edge case where these people were pushing this monetized cheating program hard to a lot of people. You have to really disrupt a games online system to warrant targeted investigation like this. As a serious gamer, I wish cheating and cyber attacks were taken much more seriously, but companies don't have the means to investigate and pursue every single infraction.
I can see if someone is suspected of being an organised criminal, such that everything he has is derived from crime. Then maybe.
But generally it sounds open to abuse. If you can just get a court to freeze the guy, then whatever your beef is you have a good chance of winning.
In this particular case the issue is regarding the control of a virtual currency, where its power (as with any other currency) depends on its scarcity. Not much new here either, what they've been doing is very similar to counterfeit printing of bank notes.
