When I paid them $10 for a month of Juxtaposition access on 3DS, it kept giving me "error 000-0000" and no Miiverse. No support email or anything to contact for help or a refund. Their database of errors said fuck-all about 000-0000.
If you're thinking to give them money to access their paid services, don't. You'll end up $10 poorer and with no service.
