This leads to a general piracy discusion which wasn't my intention.This point is valid, and I agree... But until that time comes, the freeloading banned users shouldn't have the privilege. So I say wait until they are about to shut it down before making it happen. Cuts out a lot of the entitlement from banned users.
Legit users still have the privilege of enjoying countless levels online instead of playing around with files or homebrews to inject certain levels though.
