Ok Axello, I understand your pleat, but please remove the players username, as it is un called for.
Now, for dealing with users copying your characters, there's really nothing you can do to prevent it from happening, except using the handy block button c: Out of sight out of mind. And believe me, it's not fun being copied, but you cannot report a user for copying your character because you cannot copy write a name. Although, you it can help by knowing that those people who copied you did that because they aren't creative even to come up with their own ideas.
If people are automatically calling themselves "your son" or "your daughter" ask them to take that part out of their name. If they start to argue just block them :3 Hope this helps, if you have anymore questions, just ask.
