> Does the creator need to beat the level to publish it or something? Yes, that is (at least used to be) a requirement to post to prevent something impossible from being uploaded. The game those community of people are playing is to beat hard levels, which is a perfectly fine way for someone to wish to spend their time. Edited to add that (again at least when I played last) beating the level by the creator didn't count as it being cleared by the community - you played it locally and then were allowed to upload it once you beat the level.
