This does not mean that his guess is 100% wrong.
And the best answer, in my opinion, can come from Royse777 himself or casino critique to confirm or refute this guess and remove confusion.
I also do not think that the two accounts are connected based on just an icon, although the writing style seems very similar between Royse777 and casino critique.
And by writing style you are only showing us only one word, are you going to use that to make a claim that accounts belong to the same person? Come on, there are so many people who use the same sign-off word "Cheers," Just look it up
