My Uncle did the same, and ended caught in the action at Dunkirk, which he never came home from, but only because the nut job somehow ended up going directly to battle in North Africa from there, despite it being nothing to do with the Regiment he was in. To this day nobody knows how he managed it, and it only really came out at his funeral the other year.
That's where my father was North Africa then Italy. Though similar to your uncle, my father was on a fateful mission to Norway to stop U boats, was blown out of the water en route, got rescued from the North Sea, came home then when he recovered went off to Africa. I only found this out after he died from my mother, he never mentioned it.
I can't comment on the last five years, as she has left the industry, but before this, TripAdvisor took payment from hotels for publishing and marketing fake reviews - they got a million euro fine in Italy for doing so. Someone hacked into their network and got a homeless shelter promoted to top UK hotel, by applying their fake profiling system, to prove it. Restaurants were also able to boost their rankings, via fake reviews, paid for to the website. That's not to say all reviews are fake. And I don't know if they generate income this way any longer.
They were fined for not doing enough to get fake reviews removed from their site, not for being paid to put them up themselves. They've never taken payment for reviews, but they've never done enough to deal with fake reviews (currently believed to be at least 15% of them).
