I know a large amount of people who build extensions, including myself.

It’s just a really high percentage is all, which is atypical in my experience.

People really don’t want to leave reviews, they really have to go out of their way to do so.

But I can see your point of view. Also note that fake reviews plague the industry. I get about 10-20 emails a day from people wanting to “promote” my extension with “genuine” paid reviews.

I apologise I probably should have come at this a bit lighter, genuinely just curious how they got so many reviews.
