Don't worry, guys. The admin made a blog today about those stupid reviewers. Now, there is a minimum of 100 characters to make reviews. And the admin also implements some sort of technique to identify copy-pasted jobs. Well, it may not wipe out those opportunists, but at least the admin is aware of the situation and tries to deal with it. Hopefully, the site will be better and better.
