123panYouthMember

123panYouthMember is a browser userscript that enhances and modifies the web interface of the 123 Cloud storage service. It can simulate membership-related visual elements while also exposing selected functions that are restricted or hidden by the site's front end. The script includes options for removing advertisements, changing playback speed, and customizing visible account information such as avatars, usernames, and displayed membership levels. Its documentation emphasizes that simulated membership is largely a client-side presentation change and does not grant server-controlled benefits such as additional storage capacity. The project evolved from an earlier download-assistance script and was later extensively restructured. It supports popular userscript-capable browsers and is distributed under the AGPL-3.0 license.
