It's either you rank up your account to jr. member which needs 1 merit and 30 activity points (explain in previous replies) or buy a copper membership in here.

I did try the link provided by the op but same result. Ranking to jr. member may take longer than 1 and half month if didn't even get a single merit. 1 month and half month may be enough for activity points but if merit not sure how long will get 1. Maybe op can get it sooner. I screenshot the image and uploaded to imgur here's the result. I think it's because of the image size that is why it's error but this one I only screenshot without the black background.
