Hi Goldmatters. Don't think it is any or those. You can buy reputation. It has to be commitment and being part of the community. It would've taken you years of dedication for the black belt. Quite an achievement. You can't buy one of those (maybe you can) you earned it. I saw an account today that had a reputation of 55 and she has only been on here 2 weeks. Bit like a white belt buying a higher color on the ladder.
You will be called Sensei Goldmatters from now on.
