Their UserActionTracer (UAT) may have been developed to check the seriousness with which participants took psychological data collection. But the behaviours they identified (such as 46% clicking through at a suspiciously fast rate) point towards weaknesses in all web-based surveys.
A neat summary of their findings is here.
