Hello, I think I found something interesting about @sharcrypto (shar3d | Published - MakerWorld)
shar3d found someone that fell in love with his print profiles, enough to rate all his new profiles (more than 7) a 5 stars rating in less than 24h.
Obviously all these profiles have only one rating and always from the same account.
I suspect that shar3d is using a second account to rate his profile and gain points maliciously.
Edit: There are many more proofs, I stopped here to not spam with pictures. More than 25 fake reviews on 40 print profiles
