I am still waiting for a reply. It's been a month now and I haven't received any reply nor payment.
Same here... Maybe we can contact the owners of the site we were asked to comment for? I'm not going to publicly tell everybody which site it was, but they have a user on the forum, and an active thread... Maybe they can shed some light on the situation? If not, i'm going to remove all the comments i wasn't payed for.
