Well, that review says it was left only a week before it was screenshotted, so it was probably someone who read about the Farm while reading about PG, so it wasn't ever going to be helpful as evidence or anything anyway, and probably better for PG not to have people leaving comments and reviews like that if they are just because of the PG investigation. If it was someone who had personal experience of the farm, then they should have left more details about how they knew it was a pedophile farm, or better yet, have made a police report or at least told their story and provided whatever evidence they had to the PG research community.

So I don't think this is that bad, it's when they delete the evidence that existed way before PG started last year or delete fully sourced research that connects important people, places and events, or deleting/suppressing awareness-raising posts/videos/tweets and archives etc.
