Add link in location bio

Hi all,

I see some X (adult) accounts having a link in their location bio. Does anyone know how to set this up?

Example profiles that have them:
@campeppertv
@18sexualfun

That’s usually done by just pasting a URL directly into the location field, though X doesn’t always make it clickable for everyone. Some use special formatting or shorteners to get it to show as a link. Worth experimenting with different formats until it sticks.
