Is BlankADS safe?

Medium risk

BlankADS sends browser and ruleset status to ads-blank.com and applies remote request-blocking and CSS rules.

On startup and periodic alarms, BlankADS posts its generated extension ID, browser brand list, enabled rulesets, saved date, and version to ads-blank.com. If the server response matches the local ID, the service worker installs returned declarativeNetRequest rules that can affect all sites and stores returned CSS rules. Its all-site content scripts read those CSS rules and modify page attributes or add elements on matching domains.
