You don't need permission to open a thread in the feedback & suggestions zone. If you have anything constructive to say, it's always best to open a thread in this section. We will look into it and we won't ignore it. The first thread that you linked to didn't promote fake reviews, although some users may have exchanged fake reviews, some may have exchanged honest reviews. As for the threads, we may consider allowing likes, twitter following and alexa reviews as we have a blackhat section.
