I was “assigned” a Wayspot to Review that was finally near me… and it looked good to me as well… Being thorough, I drove three miles away to visually check it out and take photos and a Gaussian Splat. Wayfarer mobile did not have the spot so when I arrived at home I find the review had expired and there is no way I could find it again. I have never had a review pop up that was anywhere close to my location so I am a total nube to the process. Are you supposed to review all those checkboxes without looking at the physical site? Did not find a FAQ on the topic of expiration deadlines, sorry if it is explained somewhere obvious.
Welcome to the forum @Nanodot99 !
The time limit is mentioned here: Niantic Wayfarer

Yes you are supposed to use the satellite and street views to review to the best of your ability. “I don’t know” is a valid response if you can’t be sure.
Welcome @Nanodot99,
We were all new once and none of this is as straightforward as you’d expect 
We are given 20 minutes to go through any reviews given to us. So while in theory I suppose you could go to close locations, but this isn’t expected.
For me personally I get reviews from my current play area, my home town (which is hundreds of miles away), and my bonus location that is in a completely different country.
Welcome, have fun, and continue to ask questions!
Wow. I’m not quite sure how to put this…
You went waaaaaay overboard. 
There is no expectation that a reviewer needs to put that much work into verifying a location. I sometimes do scrutinize local submission more closely because I am familiar with the place. But, as you’ve learned, actually going there is not realistic. All reviews have a 20 minute timer. Once that is expired, you won’t see them again.
I need to start travelling to verify wayspots from now on… only kidding. Welcome to the community.
