Hi YOSHIE,
We are a legitimate business running since 2007 and would certainly not risk our reputation by tricking forum users into our campaign and not paying them.
Also, as for the two situations you are citing, as a business which is an intermediary between clients and exchangers, we always strive to resolve any issues the clients may have (although this is a rare case since we check all the exchangers before adding them to our website). In the first situation, we asked the user to contact us and so no feedback from him in the thread. The second situation was resolved.
We hope that you will kindly remove your Negative trust once you see the first payouts.
Try resolving the past scam accusation of your exchange and also get an escrow of the funds for your marketing in the forum. If its resolved, you may get the neutral trust of the reputable people here in the forum. You can't just solve these issues by citing your business is running for the longest time since 2007.
Try picking an escrow here
