If you're not accusing me of anything, then why is this thread dedicated to these members? Why is putting them in the spotlight and the issue is nonsense? When I sign up for a platform with my favorite username already taken, I just put in numbers or capitalize some letters. We have attachments to usernames, and we do not have a copyright to usernames. It's on a first-signup, first-username basis.
You should know that if you are joining many platforms that ask for usernames.
