If you are asking me (since you are quoting me I will take it you are), I would ask if you ever had an allegation made against you that your account was either hacked or stolen or sold? If no allegation was made against you then I suppose there is no reason for anybody to suspect you are not the original owner of the joker_josue account. That is my view.
allegations made against someone are not significant if they are not based on evidence. Likewise, if there are no accusations against someone, it is not impossible for him to be guilty.
However, if you want a reply from the one who alleged Royse777 is not the original owner of the account you should consider asking the
user who created that thread what he thinks but he has not been around here since November 2021 therefore you might not get a reply.
I don't know how to take seriously anything said by one of the worst trolls on the forum. User ArcusIsidar certainly is. I'm surprised it's not on your ignore list. the fact that he attacks someone you don't like is not enough reason to take him seriously. especially if it's a proven troll.
