I don't know how important the avatar is to him, moreover, I think that the OP is not the original owner of this account.
This is my first time meeting an avid bounty hunter who doesn't know what merit is and doesn't care about rank, but cares about a profile photo.
I agree with your suspicion on the user. The account was created as far back as December, 2018. Though the user haven't been very much involved with forum discussions, he or she has been involved in other aspects of the forum as well especially the bounty section, the activity and post count on the account can attest to that. Being able to fill in proof of authentication and bounty reports properly simply means, the user has a base or is knowledgeable of what happens here and kind of knows how to find his or her way around. So, being concerned more on how to sign a message or text or how to have an avatar displayed on the accounts profile seems a lot odd.
my forum rank newbie.can i sign create forum profile picture /tex?How system create this please tell us about profile picture /tex....
The content as seen here seems to have been punctuated wrongly with complete disregard for capslock. It so much seems like the account changed hands to me. Perhaps the orientation wasn't enough to prevent these errors from coming off. Its just my suspicion.
