Because they want to make sure if that users is not the fake one so they using that way and proven effectively to fight against for someone who want to create a fake verification account, i think that is fine but for some people i think they wouldn't accept something like thatOh! That's kinda weird and you know, I hear some strict stuffs being talked about MB on way you go during verification where the person has to receive a letter from them. Some kinda manual verification or something in this computer age and it makes me wonder if the recipient of the letter MUST be the account holder.
