Addresses that look deceptively like a known brand get a warning from AdSilence — before you type anything.
Characters from other scripts look confusingly like Latin ones. AdSilence decodes the address and compares how it looks.
The list of brands ships inside the package. Nothing is queried and nothing is reported — not even which page you are opening.
You see what the problem is and decide yourself. A block without a reason would only be clicked away.
