I think the administration system of J2O is just fine. It is necessary in my opinion tha writers of reviews give a decent explanation about WHY they gave such a rating.

Image yourself this: you created a wonderful level in JJ2, probably worth a 8.5 or higher, and some noob comes up and rates it around 2.0, just for fun, without any explanation. Conclusion: you download is ruined, just like all the work you;ve spent on it. No-one will ever see your level as a real good level I am. In order to prevent these crimes, I'm glad we have a administration at J2O.
