The negative view on EVE is that CCP being a fairly small company just did not have the time and were unable to put in the effort for enough in game security for corporations. Also they didn't want to deal so much with player complaints arsing from individual issues (like escrow scams, whereby fairly new players were duped into buying worthless items for a large price - to them anyways). EVE's Devs came up with an interesting solution to say that everything in game is legal.
This is however harsh to be on the recieving end of i think. That the game mechanics allow everything to be stolen by any one individual (even the GM) is a bit scary, and whilst i do kinda like the role play argument i still think more protection should have been in place through the game tools themseleves. Reading that post you can see that many EVE corps now store things in private hangers distributed over many individuals - so the end result is that people don't trust the in game interfaces that are intended for the corporations.
Whilst the role play aspect of that is indeed fun, you can't help but feel sorry that a group of peoples work over a long time was destoryed so easily because they trusted another individual and used the intended corporate/guild interfaces. The same happens to a lesser extent in other games though, such as running with a guild in WoW and ninja looting an uber item that comes up, or even stealing from guild banks etc in DAOC. You can understand why people would get pretty worked up (imagine if WoW had been a corpse looting game, I think we would have all quit!).
On the plus side from what that thread seems to say the guy was a thief himself, so perhaps he did get his commupance

However, his whole guild/corp will have also suffered.
To go off the original subject slightly on Cerns point about real world money and games, I disagree. Anything that has a time factor (and perhaps skills factor) in obtaining equipment and items can easily be translated into real world money.
A real world example is that i could hire some decorators to come paint my house - they are more skilled perhaps and as such may get the job done quicker and efficiently, plus i don't have to invest my time in order to get my house painted. The same is translatable to buying equipment/charcters/houses/money in the online economies, it's my time thats being saved (and perhaps I could not have obtained the items myself either due to raid content etc). I can see why an ebay demand exists and I (personally) don't think you can deny the correlation between the real world cash and time/know how invested.
...though that's not a good thing. I've had the money myself to be able to buy such things and can see the logic to an extent, but have never done so. Mostly because it takes away the achievment factor for having done it yourself I think. The really scary part is in a few years time I see additional revenue streams for the creators of MMO's in directly charging you for such things. Want a level... ?5, want a sword of destruction - ?15... Want 10000 gold - ?50. It's already starting to happen, check out Sony's tentative steps
Station Exchange - they aren't selling stuff direct yet i don't think, but it's ebay endorsed by Sony.
Of course, right now we'd say we won't buy stuff like this and shun any company that does this kind of thing, I'm just worried it's the trend and if you love the games and want to stay competitive it might start to become the norm.... scary in my opinion
