We present further classifications of Gaia Alerted (Hodgkin et al. 2021, A&A, 652, 76) QSO candidates, as presented first in ATel 15138 (and subsequently in ATel 15155, 15233 and 15272). Spectra were mostly obtained with ALFOSC at the Nordic Optical Telescope with a resolution of ~300, and a spectral range covering from 350 to 960 nm. Gaia22dag was observed at OHP with Mistral at a resolution of ~600.
