On January 27, OpenSea announced a limit of five collections and 50 items per collection, after discovering that “over 80% of the items created with [their free minting tool] tool were plagiarized works, fake collections, and spam”. The decision came without warning to creators, some of whom were in the process of minting items for collections that had already promised more than 50 items, and suddenly unable to complete the collections. Later that day, OpenSea announced that they had reversed the decision, saying they “should have previewed this with you before rolling it out”.
