You actually get two slightly different warnings, depending upon whether the content is embedded or not. If you go to Twitpic directly you'll see "Google has blocked access to twitpic.com for now", a generally more gentle warning than the one you cite (which you'll see if you're viewing embedded content instead).

It's interesting there are two warnings, only one of which seems to be potentially libelous (if it was a false positive, which at this point is uncertain, especially if the content came in from an ad network).
