Possible solution: Russian make-up event for people who missed out on or did not receive rewards.
So there are many people frustrated with the Wayfarer team right now because they did not recieve rewards after reviewing Russian wayspots during the challenge. And on the Wayfarer team's side, we're told that they've done everything they've could with regards to ensuring everyone who participated got their rewards.
So, since we have a list of people who have received rewards, and a large amount of people who haven't received rewards, why not have a make-up event for people not on the list of reward receivers?
Could be over a weekend or a few days in the week, Wayfarer allows people to reset their home location to russia again, review local wayspots, and have a chance at getting the rewards again.
People who have already recieved rewards could also get more rewards, or be given less/no rewards for the make up, Niantic's call.
It would go a long way it making people more interested in future wayfarer events instead of avoiding it cause of being burned by this one.
