Captchatest.top Uses Adult Content Bait to Push Ads
Captchatest dot top is one of the hundreds of misleading websites, all of them set up with a single purpose - to push as many ads as possible in your browser.
Captchatest dot top works off geolocation and may not display the same type of lure to every user. In some territories, the website might not load any content on the page at all.
When it does load, it uses a simple adult content lure. The page shows a photo of a semi-naked woman and some suggestive text. For some reason, the page is set up to look like a Skype conversation.
The entire purpose of the page is to get users to interact with the "allow notifications" dialog box that the browser will bring up. Clicking "allow" in this prompt will give Captchatest dot top permission to push intrusive ads into your browser.
A lot of those ads can be sourced from rogue ad networks and expose the user to further misleading pages, questionable content and potentially unwanted programs. This is why when you run into a similar page asking you to allow notifications, your best bet is to simply close the browser tab.
