Why does everyone care about this? Doesn't anyone care whether our service is safe? We don't want to clarify the domain name issue. Just like a person cannot be completely naked in front of anyone.
Naked!! Do you hide some important info that may harm the reputation of your service?
This isn't a matter of privacy. There's nothing wrong with mentioning the domain name you've been using since 2018. Your responses also looks as you are indifferent and unprofessional, unable to engage with the community within an official channel. Transparency is always a key element in determining the integrity of any service.
