User blog comment:The Rim of the Sky/Skyrim Steam Workshop Now Allowing Purchasable Mods/@comment-6941549-20150425160012/@comment-1251315-20150425160154

Honestly, no mods should be paid. Modding has always been in a legal grey area, and were allowed because the mod authors never actually took payment for people to obtain them. Now, however, unless your mod is 100% original, your mod is probably going to get taken down if it's paid.
