Here's some stats about this problem in LittleBigPlanet 1 and 2 and this is about the large number of "Copied Levels" getting on the coolpage and overloading the system, and there is not enough support for getting rid-of the copied levels in LBP and in LittleBigPlanet 2 i see alot of people complaining about the large numbers of copied levels from multible offenders like Latin_Player_10 and the other accounts associated, and there is also the issue of a single person being able to have more than 10 levels on the coolpage at the same time! and we would like that limited to 3. Notes: i posted a thread on GetSatisfaction.com (LittleBigPlanet) It has been acknowleged by employees and is "In Progress" but as of now it seems like nothing is being done because Mm is mainly focused on the newer games like LBPV and LBPK. - Thanks for Reading! and i hope something can be done to adress these problems.
I recommend contacting Steveni and tasier studios and ask about Cool Pages being removed all together. with the MM picks section along with levels like LBPC's spotlight the Cool Pages serve no purpose anymore. Thats my own personal opinion about it. We have enough work arounds to where I feel the Cool Pages won't be missed. Again my own a opinpion as a LBP creator.
For now the best way to deal with this issue is to ignore CoolPages and use the MM pick list, checkout fan sights for list of level recommends. Or message Well known LBP community members for level recommendations.
