You need to do two main things:
- A confirmation post from the Freebitco.in team, three members of the team listed above.
- A position description for your account (in text) like the freebitco.in PR account has with "freebitco.in Official PR Account"
It will help everyone to know you are one of team members, and can help impersonating attacks in future too.
Over time, I think people will get to know the freebitco.in support team well. But I agree with your suggestion, having a specific description in the account profile will make it easier for customers to get to know the customer support team.
From the account name "CSFBC", I think it represents "Customer Service Freebitco.in". But first, welcome to the forum and congratulations on your new job. I really hope that many issues are resolved fairly when casinos have customer support representatives on the forum.
