Ask HN: Anyone else notice how useless Google Maps reviews have become?

I'm a "local guide" with their reviewing system, and it seems they have shadow-banned nearly 90% of legitimate reviews I've left over the years. It's quite alarming, because it seems any business can just flag a negative review now, and have it taken down to boost their overall rating, while obviously allowing companies to have 1 review accounts leave a fake 5-star rating. It has completely removed my trust in their rating system after witnessing this.
