TecEar, you're obsessed with controlling the process, to the utter exclusion of any considerations about efficiency or effectiveness.
The ODP system is designed to empower people; the processes are there only to enable people to work more effectively. And each particular process has limitations. But so what?
Is Google filled with spam results sometimes? Of course it is. But no sane person would suggest that the ODP process impose a priority on when Google searches are done! And no sane person would suggest that the editors be forbidden to ever use Google searches, because they are frequently an inefficient way to find good sites.
The exact thing can be said about site suggestions. What happens "in theory" (that is, "in your dreams") is utterly irrelevant. "In practice" (that is, "in reality") site suggestions are frequently worthless. And sometimes helpful.
So the ODP has taken the same approach, the only sane approach, for site suggestions. They are there, for when (in the editor's judgment) they might be useful. They can be ignored when (in the editor's judgment) they look like a waste of time.
But, to be fair, doesn't the submitter have the same choice? Site suggestions can be made, if he thinks it's worth his time to make them. If not, he can also use his time elsewhere.
The justification is the end-effect. Hundreds of thousands of good sites have been found through those suggestions. And if we had to wade through tens of millions of suggestions to find those sites, is that really that much worse than Google search results? And site suggestions sometimes have counteracting advantages of their own. So doing more Google searches is no substitute for judicious use of suggestions.
And that's the end of that part of the discussion. We are not, on your or on anyone else's suggestion, going to put purely arbitrary and counterproductive constraints on what the volunteers do. And that includes ALL the volunteers -- the trusted volunteers (editors) and the untrusted volunteers (submitters). WHATEVER they do that helps build a comprehensive, reliable directory, is going to be OK -- more than that, it's going to be appreciated.
