Crypto gambling sites don't need to be completely transparent, but they need to be transparent to some extent in order to gain the trust of the public.
In business, transparency matters alot as it tells who you are and what you tend to be in the long run. Being transparent keeps your customers and shows them how reliable and trustworthy you and your business is. When seen as a person or business of such, that attracts more clients because already that has done the marketing for you through your clients because they would make recommendations for your own benefit.
Some sites reveal their information to the public with good intentions while some other sites do so with nefarious intentions. Being transparent doesn't automatically translate to a trustworthy site.
It is true that some do reveal their information with good intentions while some plans to carrying out nefarious act which is not a good one. Being transparent do let people see the inward aspect of things and knowing what to do at the right time so as to avoid any ill situations.
Trust is earned little by little in various ways. This is why I feel that the team getting 100% doxxed won't solve the KYC issue.
Building a trust line isn't a bed of roses. It takes time to do so based on your records milestones achieved and that will also work when you have been available for letting ng delivering Services without any complaint and also, quick response to customers complaints and inquiries with positive results and response overtime.
So even with gambling sites stating that their team is doxxed, they won't gain the credibility right away.
It is thru the years how they will build their reputation in this business. A matter of years of existence where complaints are being handled promptly.
Sometimes I feel that a project stating that their team is doxxed just wanted to get an approval from the community without so much effort, but people already learned their lessons in this market.
And the approval which they seek for through that means would not be acknowledged by the community even if they have field the best team for the casino. Reputation takes time to build based on your services rendered. No body builds a house in one day. Everything is a gradual process which involves time and commitment.
