What Platform landing is this?

Hey,

I would post the link, but i donot want to get banned for advertising.

So ive been receiving lots of spam after accepting offers option on a credit application, when i clicked on the link for a settlement payment link, it brought me to a landing page with my email prefilled.. i pressend continue and it had the first , lastname prefilled already.

How can i do this? I am currently using mautic+pmta, however landing pages need work.
