Not Nature but Molecular Systems Biology [2], apologies, in the context of reverse docking for antibiotics discovery:

"We confirm extensive promiscuity, but find that the average area under the receiver operating characteristic curve (auROC) is 0.48, indicating weak model performance."

Derek Lowe had a post about this earlier this month [1] (which includes important qualifications I failed to omit).

This is already known. Structural models are usually not well suited for protein-ligand docking, where proper pocket modelling and accurate side chain positioning are key for the determination of true positive hits.
