A random website? Absolutely, 99.999% of the Web is safe. But we're talking about a site which is specifically compromised with malware.
With that said - "Linux" is safe by being such a tiny population of the community that browser malware generally isn't written for it. In general, I take it as a given that people have deleted/disabled flash and java plugins a long, long time ago.

Well, we don't know that, actually. The info given on the PE site say that the attacker gained access to the server and modified the database. Do you have proof that it's serving up malware to visitors?
In any case, it's an odd situation and an odd response from Project Euler. It doesn't seem like a complicated enough site to get hacked in a mysterious undetermined way.
I think I take greater risks going for a walk in the evening.
