Some aspects of hot spots or giant flares on supermassive accretion disks are investigated, with particular emphasis on the circumstances under which the orbital motion of such a spot can lead to a quasi-linear rate of rotation of the polarization position angle. A tentative interpretation of recent polarization observations of AO 0235+164 is given, and some of the consequences are briefly discussed.
