Cloud guide
BlackSakura Cloud
BlackSakura Cloud is the account file area for image uploads during open alpha. It is built like a small cloud dashboard: folders, privacy locks, direct links, reports, soft deletion, and admin moderation.
Folders
Create and organize uploads
Every account gets a default Uploads folder. Logged-in users can create more folders, rename folders, upload supported images into a selected folder, rename files, and delete files or folders from the normal dashboard view.
Folder names and filenames are sanitized before storage so uploads cannot escape the account area or create unsafe paths.
Privacy
Unlocked and locked folders
Unlocked folders have direct public links shaped like /u-media/username/folder/file. They are not listed as a public gallery, but anyone who knows the exact URL can view the file.
Locked folders require the owner or an admin login. A locked direct link returns no public file for other users and anonymous visitors.
Deletion
Trash before purge
Deleting a file or folder moves it to temporary trash so it disappears from normal owner and public views without being immediately destroyed. Trash can be purged after the retention window, currently three days.
This helps with accidental deletion and moderation review. Trash is never exposed through public direct links.
Limits
Storage and safety limits
- Current upload support is image-only: PNG, JPEG, GIF, and WebP.
- Per-file upload size is capped by the site setting.
- Total user-upload storage is capped so all users together cannot exceed the configured site limit.
- The upload system also keeps a disk free-space reserve for the Linode, so uploads may pause when the server needs room.
- Admins can view active, locked, reported, and trashed uploads for support and moderation.
Reports
Report an upload
Logged-in users can report an accessible file. A report stores the reason and details, notifies the admin/support address, and appears in the admin review area with links to the relevant owner, folder, and file metadata.
Reports are for safety, copyright concerns, harassment, privacy problems, spam, or other content that should be reviewed. They are not a way to request private access to someone else's locked folder.
