Silly Display Name Change Logo

Hey guys, well I was wondering how to get rid of the silly logo next to your name when after you change your display name.
If you don't know what I mean, here's a picture:



Just got it from Runescape Wiki.

I've seen a few friends who have done this, but they don't know how they did it, I think that it may be because they lost their membership and got it again but I'm not sure.
Any ideas?
Thanks.

 

It's just a matter of time I think, it should go away eventually after a month or so.

 

Essentially what gh0st_f4ce said.
Whenever you're enabled to change your name yet again (Which I believe is 25-30 days), it will disappear.

 

28 days and then you can change it again.

A few days after the ability to change your name becomes available again, this little icon will disappear.
