We cannot exclude overlays which will have cat/pkg not in the main
gentoo repo.  So, we should not excludea submission that includes a few
of these.  They would just become irrelevant outliers to our
processesing of the data.  In fact some of these outlier pkgs could be
relevant to our including that pkg into the main repo.

But, like you I agree that purely spam submissions would be few, if any.
