That spectrum looks like it is only noise (those are the only two peaks). Note that spectra processed with RMassBank can sometimes contain heavier peaks if they have certain adducts (up to +N2O allowed), so this should be considered in any validation. There are, however, many spectra with bogus heavy peaks that are clearly just noise (where it is clear from mass defect etc, like in this case) and maybe the (sub)formula assignment routine in RMB could be integrated into the validator to help separate the possible goodies from the baddies? What is going to be the procedure for spectra that the validator identifies as (likely) pure noise, like the example you just raised?
