The person currently operating the rby account has already claimed they are the creator and original owner of the rby account. In other words by default they are claiming they are the person known as
Kassado who is a technical coder who created Rubycoin.
Thanks, somehow I missed that part of his post.
I don't know if you compared his post history in Rubycoin thread against the most recent ones, but I suggest you to do so because its pretty obvious that whoever currently controls the account was not the person who created it, no matter what he claims. I mean, even the post you just quoted shows the difference in English level between now and 2014-2019 period.
