Oh really? Well, since I fucking love baseless accusations like this one right here, I dusted off my trusty excel and checked account creation dates of all 31 reviewers at the time of writing this.
Out of all the accounts that rated my game:
Average account age: 938 days or ~2.5 years
The oldest account: 1657 days
The youngest account: 52 days, ironically, that account left a 3 star review.
Second youngest account: 299 days
If we count only 5 star reviews, the average age becomes: 1012 days
I must say, I disagree with your definition of the word "new".
Oh, and by the way, on average, your account with it's 577 days age is much younger than those "new accounts" that left reviews. lol
Now, I think, it's time for me to leave a facepalm emote on your post and get back to creating images for the upcoming update.
