The perturbations frequently affecting the W UMa binaries light curves are usually explained in terms of bright/dark spots appearing on the surface of the components. The localization of these perturbed regions is usually obtained from the study of the light curves in different colors and by means of the so-called light curve synthesis method. The problem of this type of analysis is: i) how far we can trust the solutions and feel confident in their uniqueness, in order to better judge the increasing number of "spotted" solutions appearing in the literature, ii) in which degree the other system parameters (different from those of the spots) are affected by the incorrect determination of the spots. To answer these questions we solved a certain number of artificially constructed "spotted" light curves, corresponding to particularly critical spot configurations. The results clearly show that spot determination by photometry alone is unreliable. Moreover, in some cases, incorrect values may be derived for the system parameters as well.
