To ensure that your site doesn’t get used in a clickjacking attack, you need to make sure it cannot be wrapped in an iframe by a malicious site. This can be done by giving the browser instructions directly via HTTP headers, or in older browser by using client-side JavaScript (frame-killing). (Hacksplaining)

An anonymous polling website that prevents duplicate voting by checking IP addresses, for example, would still be vulnerable to clickjacking because it does not authenticate users using cookies. (Javascript)

This is similar to clickjacking – the criminal act of illegally subscribing customers to a wide range of content for a daily or weekly fee. South Africa is the second most affected African country by this type of mobile crime after Kenya. (Cape Town etc. )
