need help in understanding this on X

https://x.com/sexiiold?s=11 this account posts in a different way whenever clicked on the video it takes to another website & on phone it looks like it is an ad post... how are they doing it?? anybody have any idea

They’re not real video posts, just links disguised to look like videos. When you tap, the link redirects through another site, which is why it feels like an ad. On mobile it’s harder to spot since you can’t hover and see the real URL first.

how to post like this ?? do you know.. if you can help it will be much appreciated
