So noted. Be advised that some use the OASPA membership list in such a manner as you describe. Both white-lists and blacklists have their value; one of the weaknesses of a white-list is that it takes time for a journal or publisher to appear on the list, thus eliminating young journals from the list’s coverage. Blacklists are more immediate.
But you are correct; I cannot do this forever. At some point, it will end.
