After sets began to be rejected with stated reasons, Lego Ideas announced restrictions on content including the use of no new part molds, banning intellectual properties owned by competing toy companies, and adult content.[5] Ideas further restricted submissions in 2017 by disallowing any projects based on third-party licenses already being produced by Lego, such as Star Wars and Harry Potter.Since its inception, a number of sets that have reached the 10,000 vote threshold have been rejected during the review for various reasons.Any theme that relates to alcohol, sex, drugs, religious references, post-World War II warfare or based on a first-person shooter is deemed inappropriate for younger Lego fans.[8] Other projects which have been rejected include ones based on My Little Pony: Friendship Is Magic due to the property being owned by rival toy manufacturer Hasbro,[9] certain sets based on The Legend of Zelda due to the need to create too many original molds, although Lego did not completely rule out other projects based on the franchise,[10] and a Sandcrawler set for the Ultimate Collector Series due to The Lego Group's ongoing collaboration with Lucasfilm on Lego Star Wars.[13][14] Lego cited the sudden increase in projects surpassing the 10,000 vote threshold was likely due to the global lockdown amidst the COVID-19 pandemic.
