Cleancaptcha.top Uses Cute Robot to Push Ads
Cleancaptcha dot top is one of the hundreds of similarly styled misleading websites that exist for a single purpose - to push ads in visitors' browsers.
Cleancaptcha dot top will display a blank white page with a cute cartoon drawing of a robot on it, along with a speech bubble that says "Click Allow to confirm that you are not a robot". If you have been using the Internet for more than a week, you have probably completed a legitimate bot check and you know that you never need to click "allow" anywhere if the bot check is not a fraud.
In the case of Cleancaptcha dot top, it is just that - a fraud designed to trick users into allowing intrusive and harmful ads on their system. Misleading websites often work in conjunction with rogue ad networks, delivering their ads. This means that the ads displayed by pages like Cleancaptcha dot top may link to questionable content, scam sites, phishing pages and potentially unwanted applications.
All of those unpleasant things can be avoided very easily - simply never click any buttons or links on pages with suspicious names you see for the first time.
