Here's an active discussion on this same subject: Traveler/Past Owner Reviews GONE?
Alas, there's been no 'answer' from Vrbo re: their rationale, nor -- more importantly -- if there's a plan to 'fix.'
Best to stick to the thread/above for further commentary.
Welcome to this forum.
I searched this forum for "Guest Profile" and this article did not come up. Other less explanatory did, which prompted my question. after reading the thread, I can figure out why.
It's interesting that with thousands of VRBO hosts, less than 20 hosts commented on this crazy decision. I guess it's working for THEM!
