I can also see a reporting/comment/voting system being useful in other ways. It also occurred to me that the level server is also very low-end or slow. It would be helpful to some to upgrade the client/server.
I noticed that there were many spam levels with random names containing swastikas. Imo, there needs to be a reporting system of some sort to attempt to straighten out this problem. I can see this being a huge problem to some younger players, and it is generally unacceptable.
