I strongly doubt that any of the mods and admins are automatically approving new plant proposals. I, for example, first check to make sure that the species is an accepted name and has not been relegated to synonym status. I then search for the cultivar on the Web. If I find that the name is a new name for an old cultivar, a misspelled or translated name, or a new trade name for an existing cultivar, I decline the proposal and make the necessary changes in the name portion of the entry. We have trade name lines and also-sold-as lines to cover those possibilities. I never decline proposals without providing an explanation. It does take time, but the time spent is worthwhile.
Some people do provide links to a source when they propose new plants, but these are often questionable. I bought a plant yesterday, for example, that's identified on the label as a Bacopa, but it's actually a Sutera. I bought another labeled Epimedium versicolor, but E. versicolor is now a synonym for E. grandiflorum. It's the job of the database admin or moderator to recognize these common errors, which are committed by most nurseries and many plant sites.
