Ever have one of those days where it feels like the universe is distintegrating around you? Ever feel like a Roman, staring out over the city walls at the vast teeming hordes of barbarians?

Item: I already get 200 or so spams a day. Enough that, even with filtering, e-mail’s become much less useful.


Item: I’ve already blocked Windows Messages, because of Windows Messaging Spam


Item: In the past month, I’ve noticed a dramatic upswing in AOL Spam, even though I haven’t exposed my IM id any more than usual. At this point, roughly once an hour while I’m on IM, “Aimee 12779″ (or the equivalent fake address) sends me an enthusiastic IM about sex with farm animals (or similar topics).


Item: Bruce Schneier is speculating that the MSBlaster virus might have helped sink the power grid back in August.


And now:, Secunia is saying “Don’t follow links from untrusted sources.”

My first reaction when I heard Secunia’s advice was “Ummm. Yeah. That’s advice I can follow.”


But it raises an interesting question…. We already have ways to turn off “adult content” in google. Maybe there’s a way to tune search engines to only return trustworthy links.


If I hand you a link, could you tell me whether you would follow it?


What makes a link trustworthy? My first guess is that, if a link’s been there a long time, it’s more likely to be safe.
Links on pages that are part of large sites are more likely to be safe, as are links on pages that come from large companies?


But what else? What determines whether a link is trustworthy? And is detecting “links you don’t trust” really any different to, or harder than, detecting spam?

What other parameters are there for determining link trustworthiness?
