I know what you mean. I played this level that had almost 300 user created trophies, and the worst part is that no where did it say they were user created of which I did not want any.
I want the 4X trophies that will be very hard for me to get.
Oh, and I just remembered of this user created level that is a total riot, and that I bet that any poster on this forum will be familiar with.
I wish there was a way to recommend user created levels to my friends through the LBP menu.
