Is youBlock - uBlock Alternative safe?

Clean risk

youBlock - uBlock Alternative fetches remote YouTube ad-blocking selectors and applies them to YouTube pages.

When a scheduled alarm runs, the extension fetches JSON rules from https://cdn.youblock.online/rules and stores them for later use. On YouTube pages, its content script uses those remotely supplied selectors to hide matching page elements with CSS.
