Sorry but you're in no position to make this kind of judgment.
Nobody had ever heard of that forum before the mixer ban here. They are clearly capitalizing on a one-off deal to its fullest extent. The whole thing reeks of opportunism.
If you feel like spending money for a chance to make money is worth it, fine, but don't come crying here after you realize you got scammed.
I think you got me wrong, I wasn't saying that someone should purchase from their shop to shift out their trust ratings on that forum but I was basically trying to say that those who might find it useful for them to move their trust then they can do that. It's someone's own choice not mine.
Even, I haven't visited or heard about that forum before mixer ban but now I'm active on that forum and many others are also active there. They are getting many members on their forum and many mixers are moving their campaigns on that forum. I don't think that scamming others would help them at all because they will be making some good amount of money from advertising. However, I'm not advocate of that forum and that's why I won't take any responsibility.
