Sorry about that. I wasn't sure who to contact, and this post showed up in my google search. I'll contact the support in the future.
Please understand, anyone would get upset over all their games getting a 1-star review for no reason. While I understand a 1-star review wouldn't hurt the ranking, I replied to this post because you mentioned someone who abuses such system would have their rating privilege taken away, and I want someone like that to be caught and stop ruining other game devs' day.
But again, I understand this was not the right place to post about it and I didn't realize this post was two months old. Sorry for my inconsideration.
