I think you better read the paper.
"We consider the scenario of an attacker trying to generate an alternate chain faster than the honest chain. Even if this is accomplished, it does not throw the system open to arbitrary changes, such as creating value out of thin air or taking money that never belonged to the attacker. Nodes are not going to accept an invalid transaction as payment, and honest nodes will never accept a block containing them. An attacker can only try to change one of his own transactions to take back money he recently spent."
It goes on...
Come on, do any of you really think that the highly nerd-ish people at Ars don't know more about this topic than half of you that posted here? Please. They are interweb users just as much (or more-so) than anyone here.
Let's look at this problem after assuming what is clearly obvious. Ars apparently has a very difficult job finding satisfying, annoyance-free ways of earning revenue for their content. In other words, it's damn hard to purge all annoying ads. It's hard to target Mr dc29a with ads he likes, such as those containing pretty fish. And I bet none of you knew that Mr dc29a likes pretty fish, but doesn't want Wired because he already subscribed, did you? Neither does Ars. The problem is very difficult.
So how do they solve this very difficult problem? They don't. They can't (yet). So instead, they attempt it by asking (pleading) for mercy. They can't stop you from blocking the ads, so if you really appreciate the content you find at Arstechnica (and I know I do), for god's sake, subscribe! It costs $50 a year, and you might even win something in their giveaways! How many of you can't afford $50 a year for the luxury of a clean, add-free, fast-loading technical website that you visit 10 times a day? You can't spend 14 cents a day for that?
If you can't spend 14 cents a day, how about turn your blocker off every other week? This is about helping Ars out without hurting yourself. So find a balance. Please.
Yeah, it was a chauvinistic comment about the collector of a data set, a set that implied the comment was stupid to begin with. And even funnier when it turns out the data set was created by a man.
*sigh*
