What script is used by the site?

Question

CMS

Hello. I need your help. Tell me what script or what is this module? Uses a survey: 3porosenka.ru/sex-test/ don't think it's advertising. The meaning in it is that the user passes the test, and the test answers are sent to the person who gave him this link, and therefore the user now receives his link in order to "play" the other. Interested in what this survey is written on, or is there a ready-made solution? Thank you.
