Open3DLab says Roblox crawler downloaded 145.5 GB of models without permission

Open3DLab, SFMLab and SmutBase say that on October 15–16, a crawler claiming to belong to Roblox read 18,926 project pages and fully downloaded 1,027 files from 712 projects, totaling 145.5 GB, of which 345 projects were adult content. The sites discovered this on October 18, banned the crawler, and contacted Roblox twice using the email in the user agent but received no reply. The sites speculate that the data is used for Roblox's 3D foundation model training, but say they cannot confirm this, and publicly demand that Roblox explain the purpose of the data, whether the files have been deleted, and whether it respects creators' licenses.
