It is interesting that when Buyers leave their honest reviews if it is under 3 stars that it is being removed. So unsuspecting Buyers are being given the false impression that a theme is good because when you look at the review you see only 5 stars and may be a 4 star. Only to be fooled when you do purchase the theme, that the theme is either broken or full of bugs.
Unfortunately, this marketplace have become an outlet for hustlers. It is like no one is really checking these Wordpress Themes before they are put up for sale.
So Authors and Envato make money while Buyers are left out of pocket with a theme that do not work as the Demo.
As a Buyer you want to get your project off the ground so you try and try with a buggy theme and then out of frustration and wasted time you inevitably give up and purchase another theme based on the reviews and again you end up on crappy street because the reviews were false.
It is a vicious cycle where as a Buyer you always loose. When I first joined this Marketplace I used to tell everyone about it because I thought it was a Gem of a website, but I no longer share this view. This marketplace has become a corruptible marketplace full of new Beta Testers, with most of them apparently not having a good command of English. This is reflected in their themes language, documentations and their support responses.
