Hi there,
Most definitely seconded to what Casey said. Linkscape doesn't filter based on spam, so the authority you see passed here is skewed in terms of real world effectiveness in Google. Squidoo really is one of the most awful dens of spam online. Interestingly though, I was just taking a look at the full list spreadsheet of sites hit by the Farmer update (according to Sistrix's data) and Squidoo isn't mentioned.
But it really is awful. Stay well away
