Surveymonkey link

Does anyone know how people are getting the exit link from Surveymonkey? Do you really need to be paying $1000 a year for the $99 plan to enable a custom thank you page?

Heres a bit more of what I'm talking about

There is heaps of surveys that are indexed on Surveymonkey that have this exit link, it's a d0follow back to the brands site. Some of the brands that have them don't look too big, so can't see them paying $1000 a year just for that?
