The issue with having the split based on each name is that I could do something like GreatName, it gets Short Listed. I notice this and then I come back with the following submissions, GreatNames, GreatestName, and so on. You see the problem? Those submissions aren't really unique, they are all based on the shortlisted name, just different variations of my first submission. The reason I came back to add variations of my high ranking name was to pad my Short Listed names so I would get more money if the contest happens to be abandoned.
What happens when only 10 more people start padding their high rated submissions? The CH receives hundreds of very similar submissions and the abandoned contest situation is more likely to occur. After a while, more will catch on to this little trick and soon the contest will be 20 names with 200 variations.
As the system is now, I create a name and variations of that name are entered in one submission. I can easily submit each name separately, my submission limit is high enough. But why waste my time and the CH's time and create more abandoned contests?
