Best Change has changed the title in his reply and it appears in yours as you have quoted him.
Do you worry about that?

Not at all. The only thing that had caught my attention was that Jollygood's reply was titled "Best Change is not a scam", but then I understood that it was because he had quoted you.
What I see positive in your answers is that you do not hide and give detailed answers to everything. But there is one main issue that you have not addressed:
What about Openchange's KYC. People have the right to know more details about the company, if it is even registered.
If you are in favor of KYC and blacklisting for legal reasons, at least the entity you support doing those things should have a more extensive published data on their website other than an email.
That question you have not adressed in your detailed responses in this thread.
I am still waiting for a response in this regard, and I think I am not the only one.
