If an author sees their level listed here and does not like that, I will remove it.
Basically if the maps are released, they can be reviewed, but I will respect the wishes of the author (or authors) and remove a listed map if requested.
In 2020, with so few new maps being made, I feel like uncovering "buried treasures" is one of the best ways to help keep supporting LvL (in addition to donations) with new content. And since most people have never heard of these old maps, they'll basically be new to most people anyway. Of course, as Tig said, one should check the readme first to make sure redistribution is okay (there was one map I found that I really wanted to send in because I thought it was really cool, but the author required permission to even redistribute it for free, regardless of whether it's for profit or not), and of course one shouldn't send in betas or alpha builds, something which I'll fully admit to having made the mistake of doing years ago but recognize and try to avoid now. So it is possible to still respect the authors and send in their maps (and keep a high level of quality in place while doing so), because most authors are generally okay with having their maps redistributed as long as it's not for profit and the readme file / map assets are left undisturbed, with few exceptions like the one I mentioned earlier, which I'll gladly respect.
