I have an xcart store with about 150 products that I launched about a week ago and I found that a user with this ip address 184.108.40.206 rated 80% of my products with 1 star. As a new site, this caused the ratings for a lot of my products to drop significantly across the site.
Which is no big deal because I can delete ratings from spammers, competitors, etc. and have already removed ratings from the 220.127.116.11 ip address.
What I found curious, though, was that the ip address belongs to Google. If all products were rated the same I would think this was googlebot but some products were rated with 3, 4, even 5 stars but most were rated with 1 star.
Why would Google be rating my products? Is this a person or a bot? If a person, why would they take the time to rate products on my site, what good would it do them? If a bot, why would it rate products, and especially why would it rate them differently?
